Hey, I posted a thread on another site and they did not help at all and I know tihs site is good for alot of things that I check out. This is my problem I am having... What I was wondering is that my Memory Bus Speed atm is 132.5 when it is suppose to run at 200. The reason its low like that is because im my bios I manually set the memory to DDR200(100mhz). With the setting this low I can achieve the highest overclock on my cpu. The higher I go with the memory timing, I.E DDR266(133Mhz), ddr300(150Mhz) I start to only oc it less and less. So at the moment my cpu is at DDR200(100Mhz) with CPU freq of 265x10 which makes my memory bus speed at the 132.5. What I am wondering is will that low of a memory bus speed make an impact on performance? I raised the volts on the cpu slightly and have not messed with the voltage on the ram or anything because of the no OC. Recently I have been gettin a few BSOD and such and I was just wondering also could it be because the ram bus speed is that low? I received the chip not too long ago so I wouldn't think that is the problem. If anyone has any insight or can further shed some light for me that would be great. Attatched a pic to maybe clarify what I am trying to get across here...if its the memory sticks that are a problem then that maybe might be what I was thinking from the start. They are some crappy sticks lol.
Can't really tell anything from the pic because it's all messed up. YOu know you should try running Prime 95 to see if it is stable or not. I will probably tell you it isn't, then try running the memory at normal speeds and try Prime 95. If it's stable this time then it was your memory.
I ran prime95 and everything seemed stable about a month ago. I could try running it again and see if it still is... But pretty much all I am wondering if running the bus at that low speed with the cpu high like that will there be a conflict somewhere or is there a way I can get the bus timings back to 200 with the cpu at the setting that it is currently running? Sorry for the confusing questions? I have aim if anyone wants to try to help me out and make it easier to type >< lol.
I guess your memory could bottleneck your CPU if you run it low. I think you would probably be better off runing the memory at it's right speed, as it does make a difference.
What type of test should I use, the benchmark or the torture test? With the torture test it looks like it will take a while lol...?
Ok I ran the benchmark on the settings I had it at and then reset the ram + cpu back to the default settings is this was the results.

Torture test, it may take from a few minutes to hours. At least leave it on overnight and go to sleep, you need it.
Well see thats the thing... When I run the Memory bus at default speed, my cpu OCing is limited but when I drop the ram bus speed I am able to OC the cpu higher the lower I go.
It's faster definitely, but if it crashes on you then what's the point? Try getting the best OC you can with it being stable at the same time. Benchmarks are fine but run a game, and use fraps, see what the difference is. I'm going to sleep now, so peace out. Talk to you tommorow.
Well I ran prime overnight on torture test while sleeping and it ran for 9 hours with no errors and passed all tests. So I assume my ram is not faulty or anything. My pc hasn't been crashing recently at all.
Well then you're good to go! If the benchmarks turn out better and its stable then all is well. Have fun!
