The Official OC (OverClocking) Thread!

haskins69,
Don't get caught up in that 4.0GHz thing. I let myself do it (Ego) and hurt my E6750 in the process. It took almost a year for the E6750 to completely die, as I had to keep increasing the voltage every month or so, until I finally got to 1.49v. Even then, when it did die, it didn't just stop working, but it starting corrupting files and other strange things, until it finally refused to work at all! I tried re-installing XP-Pro, but got error messages saying that the files were corrupt! I lost fully half of what I had on the computer. Thankfully I had a backup of all my programs. If it runs good at 3.8GHz, I wouldn't push the issue, especially on that particular motherboard. Just some advice from an Older Skinny Guy! LOL!!

Best Regards,
Russ

 

Something you might find funny, the highest I can get my Q9550 to is 3.95Ghz...

 

Their hardware is generally fine. Their customer service is what ive heard a lot of negativity about

 

Their customer service is dire, though Gigabyte's is far from exemplary. However, the overall build quality of Asus boards scales with price. The top end Asus boards (excluding the Strikers) are usually pretty good. Their cheaper ones though are absolutely dreadful. Other companies like MSI and Gigabyte in particular build even their cheapest boards properly. I've a lot of respect for the £25 MSI boards that last for years, unless you spend more than £100 you'll be lucky to get an Asus board to last the 12 month warranty.

 

thank's for the reply's folk's I was beggining to that this motherboard was making me unpopular too........

sammorris
can you explain memory multiplier ?

I'm assuming if memory is unlinked that it doesn't affect the outcome
vcore and north bridge I under stand
I only upped the vcore one setting 1.43v [it start's at 1.425v] [If I remember right] to get to 3.82Ghz
northbridge I set to 1.52v but I don't remember how much a increase that was not much I'm sure
ASUS tech said leave it Auto

I got to 3.82Ghz so easy I really thought 4.0Ghz would just be a setting or so I was missing or some thing

I just didn't want to push it till I had heard from others about it I posted here
http://www.xtremesystems.org/forums/showthread.php?t=175399&page=59

a striker II formula overclocking forum and those people won't even answer , it's like they got a secret that they won't share
but many have made it to 4.0Ghz with 2.66 Ghz CPU's so I thought going there with a 3.0Ghz CPU should be easier , hell some of them are hitting 4.4-4.6Ghz with 2.66Ghz CPU's [ I read all 59 pages of forum]

and no right now I don't want to keep it there I just want to learn and do it then sett it back to stock hell 3.0Ghz is plenty fast for the games and programs I use

and power and heat this thing uses and creates well your right on old one at least this one is much cooler running but of course power consumption is still high

could some one look at the settings I used to get to 3.82Ghz and give me a hint ?

so I don't smoke some thing
I was easing it up in 5MHz increment's IE: @3.82Ghz=425/1700 FSB
3.87Ghz= 430/1720 FSB this is where it folded with vcore at 1.43v
I have lot's ofroom to go higher just didn't want to try till I asked

original time it took less than a hr to get to 3.82Ghz of course I didn't run prime95 every time I went up 5Mhz

any help would be well recieved

as far as ASUS product's go In my opinion they seem ok unless the name begins with "STRIKER" and service I've heard suck's but they were helpfull and worked well with me on this matter the last RMA is the only dealings I've had with them the other 7........LOL...were RMA'ed though Cyberpower

thank's folk's

 

Wow guys! I cant see the need in overclocking this phenom II! Its faster than BEEEEEEEEEEEEEP! I cant imagine i7 being quicker! NO, that was not a fanboy comment. Infact, eventually I wouldnt mind trying my hand one more time at intels best. Ok, perhaps I can IMAGINE! But I certainly dont see the need! Perhaps though, after a little more acclamation, I can engage in my own testing. <-----Thoroughly Impressed!

 

4.4-4.6Ghz on that CPU is exceptionally difficult, the reason why most people don't tell how they achieved results is because they didn't actually achieve them in the first place.

 

I'm not asking how they got to 4.4-4.6 and I don't really care it's just they start at either 2.4or 2.6 and get that far I figure to go from 3.0 to 4.0 should be well not easy but much easier than going from 2.6 to 4.4

right?

and your probaly right maybe they are just talking shit !!!

 

With a good board, 4Ghz from an E6850 shouldn't be too difficult, but you need good RAM. With your board though, I'm not sure.
The normal front side bus speed of the E6850 is 333 (Core 2s use a 4x Bus multiplier to achieve 1333mhz actual bus speed, but this is irrelevant here).
Thus, at normal speed, if you have 800mhz memory, you need to use a multiplier of no more than 2.4x. (333x2.4 = 800). If you have 1066mhz memory, you need a multiplier of no more than 3.2x.
When you overclock the processor, you increase the bus speed, however. To reach 4Ghz you change the bus speed to 444. Since the minimum memory multiplier is 2x, if you only have 800mhz (PC6400) RAM, you are unlikely to succeed, as your RAM is being overclocked by 11% to reach that speed.

 

memory is unlinked !!!
and to hit 3.82GHz my FSB was at425/1700
so your either not seeing the unlinked or I'm missunderstanding what it means
and the fact that I made it to 3.82GHz with DDR-2 800mhz was more luck that ablity

right ?

by the way as soon as I have the money I'm getting 1066Mhz ram
just a shame to put more money into a board that destine to die soon .........LOL

and when I upgrade it I'm going with DDR-3 motherboard

hopefully a core i7 board

or if it's a while [probaly will be] what ever the next great thing coming down the road is

but I'm a Intel man [ sorry AMD people] so that's where I'll stay unless AMD does something really great which is unlikely Intel has too much of a lead right now

w/ 1066MHz ram using you formula 3.2 x445 [what it takes to reach 4.05Ghz] that calculates to I need 1424 Ram speed
seems impossible fastest DDR-2 on newegg is 1200MHz
which probaly won't work on this RAM picky prick !!

and isn't 1066Mhz ram just overclocked 800Mhz ram ?
I read that some where don't ask where I'm on this box 12-16 hr's a day

and I'm not on porn sites but usually trying to learn so I can help myself , friends and people who will pay me !!!

Just re-read your post what's the stock memory multiplier ?
2.4x ?

I ask because unlinked I did hit 3.82 so I was thinking if I go in and and set multiplier to min. 2x and it is less than the unlinked speed then maybe I can get there or at least closer in 5 Mhz jumps that's 4 jumps that may at least get me to 3.915Ghz = 435/1740 with this Ram
Damn corsaire Dominator 1066Mhz 2x2Gb is $89.00-$117.00 with fan kit

 

Unlinked memory is no magic bullet, it can't push beyond what fixed multiplier boards can achieve. If you do only have PC6400 I strongly recommend you change it to reach 4Ghz.
There's no real reason to go DDR3, it doesn't offer any advantages, it's just unfortunately mandatory to use i7 - the difference between i7 and Core 2 Quad still isn't very much though, especially as far as games are concerned.
As of now though, you are right, Intel are still way ahead of AMD.

You don't need to use 3.2x multiplier at 445, that's just what you CAN use to get 1066mhz at default 333. You lower the multiplier when you raise the bus speed to achieve the same memory speed.

It is true that 1066mhz RAM is just overclocked 800mhz memory, however, it is subject to stringent testing. I have yet to hear of any stick of RAM advertised as PC6400 that has been able to reach PC8500 speeds through overclocking.
The memory multiplier is automatically set to whatever keeps your memory at its correct speed, since your RAM is 800mhz, it'll be 2.4x at 333. When overclocked, as far as I'm aware, 'unlinked' memory does not sink below 2.0x, so you'll probably be at that, and 425FSB means your RAM will be at 850mhz, which most good PC6400 can achieve.

You don't need the fans with the dominator memory, they run plenty cool enough as it is.

 

thank's sammorris

now I'm finally getting the answers I need

I guess it partly how I word the question and after asking about this ..OH about 100X on other forums I finally got it right

thank's I'll try and find the money to get the 1066 Mhz Ram

one more question how stable and hard to use are faster DDR-2 rams ...say well let go for broke 1200 Mhz?

 

You can buy 1200mhz stuff if you like, but it's not always guaranteed to work with every board, and realistically, there's not much to gain with using it over 1066mhz RAM unless you have a very high bus speed CPU, or are going for a huge overclock (only really applicable to the E8500/E8600, and the QX9770)

 

cool Ok I under stand it would be a waste of money and cause trouble I don't need since I'm only trying to get there not stay there

 

Ok I sat around last night and had some thought's which I believe were confirmed by anouther person on "tom's hardware"

so here you go:

I thought if you up voltage to CPU to overclock it [giving it more power to go faster] and if you have to raise voltage on memory to install 1066Mhz ram [usualy from1.8v to 2.1 v for 1066 ] which gives it power to go faster

then if I turn down multiplier and raise the voltage to memory then I should be able to get some more out of it

maybe not 4.0Ghz but I was hoping to hit maybe 3.91Ghz 435/1740 FSb or 3.96Ghz 440/1760 FSB

please check my thinking and let me know

 

Raising the memory voltage will help how far the memory can be overclocked, but nothing more. Raising the CPU voltage is a critical part of overclocking and I'm surprised if you haven't needed it so far.

 

I did but not much only from 1.425v to 1.43 v

I'm probaly gonna try the memory ratio @ 2x which would be 2x 445FSB =890 memory speed or 4.05Ghz CPU

which with value select [cheap] memory might not be possible
but it's worth a try

and if my memory is the issue becaus it's to slow and if raising my FSB will overclock memory also

doesn't it make since to up voltage on memory?

 

Yes it does, but RAM won't take kindly to much of a voltage increase and it does not jump hugely in overclock performance from extra voltage, it certainly won't hurt though.

 

OK thank's again
I got some real life stuff [non-computer] to do so I won't try for a week or so but I'll get back to you when I do

thank's again

 

Just poppin' in to see where everybody's at on the overclocking relm of things. Who's OC'n 45nm LGA775's and who;s moved on to current LGA1366 OC'n on the hot new X58? I love it so far.

I am still around but I will keep my "Two cents" on the side lines to the long term popular and regulars.

Have fun guys and overclock them mother boards till it "HertZ"! Lol!
