Some Help with Q6600 & Corsair Dominator

This discussion thread has 24 messages.

After putting my system together, I noticed that my CPU was running underclocked. So, I tried to get it to stock speed, and I was having a problem with my RAM.

I could not get my FSB past 270MHz because my RAM was then running at about 1100MHz and I guess it can't take that.

I started messing with lots of settings and the only way I can get my CPU speed up and run my RAM at near 1066MHz is to set my FSB to 400MHz. I was able to get my RAM stable at 1064MHz. The only problem is that now my CPU is at 3.2GHz with a 1600MHz FSB.

Is this going to affect the CPU life?

My Idle Temps are: 26/24/22/24
My Load Temps are: 49/48/45/45

I read that vCore being too high is bad, so I lowered that to 1.28125 or something like that....

Newer chips (Including the Q6600) include speedstep. Speedstep is a power management device of the chip that reduces clock speed and power consumption when the CPU is idle. Generally it is good to keep this on and this is likely what you are seeing as the chip is sold at its retail clock speed. You're right about voltage though. You risk a lot more with voltage than you do with temperatures as the chip will throttle itself if it gets too hot and can generally take temperatures far higher than most people will admit to. Still though, I would advise running temps up in the 80's and 90's.

Load temps are fine. My VCore under load is 1.256 and 1.144 idle. You can google official Q6600 threads on some other sites to get an idea of where people are topping out their voltages at.
I bet it was the multiplier....

2133/8 = 266.625
266.625 * 9 = 2399.625

So probably setting the multiplier to 9x would do it.

It ran at 1600MHz idle and 2133MHz when I ran some software.

I lowered my vCore one notch back, so I am at 1.2725 (I think that's the number :P)

I also lowered my RAM voltage to 2.08v. It is rated at 2.10v.

If leaving my CPU at 3.2GHz and 1.2725 volts with RAM at 2.08v will not affect the life, I will leave it there. At stock, my CPU was 1.3125 volts and the RAM at 1.80v. So, the CPU is now lower voltage and the RAM is higher, but the speed of my CPU is 800MHz higher with the FSB 533MHz higher.

Will my setup now affect the life of the CPU? Should I try and push voltage lower, or is 1.2725v fine? Will the RAM voltage affect it's life? Here is what everything looks like from EasyTune (BTW is this a good monitoring app for voltage?).

Sorry for the long post but this should give you a good sampling for OC and voltages.

Wow, thanks for the list! Lots of data there.

It looks like my settings are similar.

What is a good temp while running Prime95? It is running now, and I am getting 45/44/40/40

Idle is something like 23/21/19/20 (I set vCore 1 notch below 1.25000).

Now, with voltage, is it dangerous to have voltage too low? For instance, my CPU has a VID of 1.3125. Is running it below this value bad? It seems like dropping from 1.275 to 1.25 dropped temps about 4 degrees, so it is possible that dropping voltage more, would drop temps below 40 degrees while running Prime95.
You want your voltage as low as possible. You won't damage you equipment if you take it too low, you'll just have an unstable system. Your temps are great. Mine max out around 65, and some(few) people even run them into the high 70's 24/7.

Thanks for the info!

The temps are probably so low cause the case is opened and laying on it's side. I don't have a SATA HDD, so the DVDRW and HDD are sharing the same IDE cable and the cable is not long enough for the DVDRW to fit in the case :P Also, I tightened the hell out of the mounting screws on the Tuniq (come to think of it, I don't thing the case will close as the Tuniq is HUGE).

I had to up voltage a bit though. Seems like the RAM has a problem with my setup. Strange, because it is running at 1066 which is technically default...

I ran Prime95 with small FFT for 4 hours and it was fine. With Blend, it messed up in between 30 minutes to 5 hours (wasn't home when it failed). I assume failing in Blend means that there is a RAM issue also the system went more stable when I upped DRAM vCore to 2.08 from 1.8. Been running it for 1 hour so far and it looks good. Temps are holding at 45/43/40/40 with vCore at one notch up from 1.2500v (BIOS).

With system stability, does that just cause programs to fail if I overwork the system, or will it cause hardware problems?
If your voltage is too low I would assume your system would spontaneously shut down under high load or fail to boot in the first place. I suppose it might just hang the system as well but not individual programs. You'll only want to be adjusting one thing at a time though if your system isn't stable because of your memory fix that first. And then see how far down you can tweak the CPU voltage before you run into problems.
It seems like it might need more voltage. Prime95 blend got an error in core 3 at 2 hours 15 minutes.

The system can boot with lower voltage than what I have, but it seems to be less stable. I think when I tested it with small FFT, it was with lower voltage and it was fine for the 4 hour test. With DRAM at 1.8, Blend failed in about 3 minutes. DRAM to 2.1 it lasted about 30 minutes.

When I upped vCore 1 notch, it failed while I was gone, but the system rebooted, so I could not see how long it took.

The most recent is the 2:15 session with core 3 getting the error. My guess is that vCore should be raised more, but I don't know much about this. I don't want to take the RAM higher than 2.08, because in the Motherboard it shows pink, which I am assuming means an overvolt or at the very least, risky voltage levels. The RAM does go over 2.1 in Windows when it is set to 2.1 in the BIOS.

Maybe I can do more testing tomorrow with vCore up 1 more notch... Are there any other settings that I can tweak to get the system more stable? There is MCH and ICH which I think are northbridge and soutbridge... They are stock at 1.10v. There is also ICH I/O, which is set to 1.50 at stock.

There are also advanced CPU setting which include CPU skew and MCH skew. I have no idea what those mean. SHould I do anything with that?
I did an overnight test, and it crashed at some point (man I wish there was a log of some type). I ran 2 instances of Blend to use 3.8GB of RAM and 1 instance of Large FFT to max temps.

There is a chance that there is some type of log as there is something called results.txt and they are all a little different, but it does not show a crash time Here is an example of one (looks like one of the two Blend tests):

You do realise your CPU wasn't running underclocked before right? It's intel's power saving feature, the multplier drops to 6x (1.66Ghz for a Q6600) until it's used, but once you apply load, it instantly changes to full speed, no delay noticeable whatsoever.

Your vcore is extremely low for overclocking, 1.4V is common for a Q6600, so trying to get below 1.25 is only going to cause issues.

It was underclocked, but not FSB. The Multiplier was set to 8x.

I noticed the power saving stuff and that was the first thing I turned off. It still only peaked at 2133MHz and I was a little stupid in not seeing that the multiplier was set to 8x :P It's the 2nd setting I think in the BIOS :P You should see me try to find my glasses.... Sometimes, I search for 5 - 10 minutes and it ends up I am wearing them.

Prime didn't have an issue yesterday. I ran two instances of Blend so I can use 3.56GB of RAM and it was fine for 10 hours. I didn't want to leave it overnight again because the fan on the Tuniq is louder than a vacuum cleaner! I'd probably go deaf in my sleep :P

Temps peaked at 47/45/44/44, but averaged about 45/43/41/41.

I raised vCore to 1.26875v; MCH to 1.16v, and ICH to 1.20v (all settings done in BIOS). Those were the setting I ran Prime95 with yesterday.

I also tried TAT to see what max Temp was and Core 1 peaked at 49, core 2 at 46. That doesn't test more cores, so I didn't run it too long; like 5 minutes.

I ran OCCT for 1 hour 5 minutes that showed that it was stable, but the reason I really did that was to see all the graphs :P There was one temp that went from 17 to 37. Don't know what that was...

Clock is at 3203MHz; FSB is at 1601MHz and idle temps are 24/21/17/20. So, all of the overclock comes from FSB. The RAM ratio is 4:3 (2.66 in BIOS), I guess 400MHz x 2.66 = 1066MHz or 400MHz x 2 x 1.33 = 1066 ???

What kind of issues can arise from low voltage? Can the components get damaged?
That is correct, that is how intel's powersaving works, but it's odd to see it at 8x, I would have expected 6.

Low voltage won't damage anything, you just run the risk of crashes. It's high voltages that are preferred for stability, but cause risk of damage.

The way it seemed to be going was 6x at idle and 8x at load, so the processor never got faster than 2133MHz, but the idle speed was 1666MHz or something like that.

WHen I shut off power saving, it was at 8x and I didn't notice that the multiplier was set at 8x in the BIOS. This is what caused the initial issue. I was close to returning it, but then I thought about all the trouble I went through installing the Tuniq (that thing is HUGE) and I thought, why not overclo9ck it to 2.4GHz... Really, all I had to do was change the multiplier to 9x. I don't know why default was 8x.

It kind of seems possible for this chip to make it to 3.6GHz. All I have to do is change the multiplier to 9x and probably pump some major voltage into it :P Actually, I'll give it a shot and see what difference it makes in CPUMark (Passmark). Right now it scores a 4315, which is around what a QX9650 scores. Of course this is just a benchmark. I can do my own testing (at 3200MHz) once I get a SATA HDD.
Ok, so I upped the Multiplier to 9x and upped the Voltage to 1.4250v something (1.440v in CPU-Z). Idle temps are pretty low still:


Load temps are 52/51/48/48 (actually don't seem too bad).

CPUMark was 4836, so a jump of 500 points. This is about the level of a QX9770, so that's impressive for a $180 CPU :P

Actually Memory Mark and 3D mark also went up about 10% or so. I guess a faster CPU helps everything a bit.

I will take it back down to 3.2GHz. Maybe if I have time I will see if I can get a stable setting at 3.6GHz, but I just pumped the voltage up so I could boot on the first try.
If you can even boot at 3600, you've got a better CPU than me. I had to use more than 1.51V (which is as high as I wanted to go) to even POST at that CPU speed.

I guess I got lucky. I don't know how stable it would be at 3600 though. I just ran Prime95 Blend for 5 minutes to get load temps. I didn't want to push it too much at that high of a clock speed or voltage.

Wow, you had it at 1.51v? There is a chance that your booting issue has to do with the RAM. All of my booting issues were RAM related. If you'd like I can take pictures of my BIOS settings (or if taking a picture doesn't work, I can write them down in order) and you can give them a try with your setup and see if you can get it to boot at less than 1.5v at 3600MHz.
That's quite possible, as I had all four slots populated when I was using that CPU. The memory was timing loosened and overvolted, but I suspect that the FSB was the limitation when all four slots were filled.

I didn't even think about that :P Yeah, 4 slots filled makes it more complicated as there are more variables, so it is harder to pinpoint the culprit. It seems like you made a beast of a build though!

So far, I am very impressed with the Q6600. I can't wait till I get a new HDD so I can finally install something that will use all 4 cores.

The only thing I did testing wise was correcting IFO navigation using IFOEdit and it was slower than my 6 year old system :P IFOEdit only uses 1 core, so there is no benefit from having a Quad. Also, I think the HDD is starting to show a little slow down sharing the IDE cable with the DVDRW. I would really be able to tell if I use FixVTS. That always works at 100% HDD speed. I used to get 54MB/s on my old system and I think that is max speed for ATA133 drives. I guess I can use FixVTS on the DVD I was working on last night.
I'm not sure about there being a limit on the speed of ATA-133 explicitly, but IDE Hard drives are old, so they may not run much faster than that regardless.
As far as the system goes, I only changed from Q6600 to Q9550 because the 6600 wasn't enough to run Crysis Warhead on Enthusiast, and I found a reasonably priced E0 stepping version of the CPU. They seem to be popping up into mainstream now, but at the time they were rare, and I didn't pay over the odds to get one (£250 to be precise). The way PC parts prices are going up lately, it's just as well...

The ATA 133 limit is technically 133MB/s, but that is maybe burst speed or something. I think 50 - 60 is common. Maybe burst speed approached 133MB/s?

The Q9550 is the Processor I really wanted, but I could not afford to put any extra money in my setup. The price you paid is good, especially in UK. I would have imagined it being over 300GBP. Crysis WH is one of those games that is CPU limited, so it makes sense that the Q6600 would not cut it. Especially with your video card :P

I was wondering, my motherboard says it is rated at DDR2 1366+, but it supports FSB up to 1600MHz. However, the overclocking tool that comes with it, has an easy setting that takes it to 1760MHz. I thought raising FSB over motherboard spec was bad.
The Q9550 is only £250, but I got the E0 stepping, back when all you could get from retails was C1s. The E0 is basically a Q9650 with a lower multiplier, and is know to overclock well on a low voltage, which mine has done. While I didn't pay any less than usual for my CPU, I guaranteed myself a (at the time) rare version, which on that basis would technically be worth maybe £60-£70 more than I paid, as the Q9650 is nearly £400.

If there's one thing you need quad core CPUs for, it's dual graphics. The exceptional CPU load of Warhead, plus the CPU requirement of running two GPUs in it drops my minimum frame rate down to about 17 with a 3.5Ghz Q6600, it's about 22 with my 3.65Ghz Q9550, not ideal, but playable, were it not for the stuttering when loading textures. I'm possibly attributing this to running a 32-bit OS, but in Vista, while the game performs better, the game speed is not uniform, which is very disorientating.

As far as overclocking the FSB beyond the motherboard's rated speed, it has much the same effect as a CPU, it's not going to justify a warranty return if you can't surpass a certain speed, but it's not going to do any harm unless you up the voltages too much. It is however, a source of instability - the maximum FSB my board can achieve is 455, regardless of any other settings, simply because I use a quad core CPU. That is the limitation of my chipset (X38) specifically, not my particular board.

Wow, that was a good deal! That's probably the best you can do without breaking the bank :P

As for my CPU, I think I will leave the FSB at 400MHz. It makes the most sense to me as getting the RAM to 1066 is pretty simple. The next logical step (to me at least) would be 533MHz with 1:1 RAM ratio, but I am guessing 533MHz is insane for this CPU/Motherboard combo. I don't want to deal with stability testing any more either.
Oh, I broke the bank alright... :P
Even the P45 chipset can only reach 505mhz FSB with a quad core, so 533, never going to happen :P
