Want to OC just my CPU - Page 10

post #91 of 127
Good job!

I see that cpuz says your at 1.55v? Personally I wouldn't go any higher than that because I like to keep my cpus for a couple years. Your cooling seems to be doing a good job though so that's good. Try using coretemp also just so that you can compare the two.

If you'd like extra performance, you could drop your cpu multi to 14x and raise the fsb back up to give you 3.3ghz. This will obviously make your fsb higher than it is now, giving your memory an overclock as well. I know you originally didn't want to oc your ram, but I don't see a reason not to

Keep up the good work.

The thing with my voltage, in the bios it's set at 1.45. When I go into windows it says it is just a touch higher, like 1.475. When I do a test with Prime95 it jumps up to 1.55. Not sure what the deal is there. I have checked the voltage with 3 different progs and they all say the same.

My memory also has a slight overclock, I think about 415. I was thinking of upping my memory voltage to 1.21 and tightening my timings to 4-4-4-12. I hear I can do that easily with the memory I have. What do ya think?

I found that with by board/cpu it also jumped up under load. I'm not entirely sure why it does that, but I would take into consideration your highest voltage and use that as your limitation.

With the memory, did you mean 2.2v? Most of the good DDR2-800 memory is rated for 2.2v and 4-4-4-12 timings. You may find that you don't need the full 2.2v to get stable at 4-4-4-12. If you're happy with their clock then I say go for the timings. But usually a balance of frequency and timings is best. This balance changes from stick to stick and frankly, I don't find it worth my time for the things I do. You can see my memory settings in my sig I think. I'm running at 5-5-5-15 at around 925Mhz on 2.2v. I just went with a higher clock and looser timings.

My memory is rated at 1.8v, and is set automatically to 1.9 in the bios. Link here...http://www.microcenter.com/single_pr...uct_id=0274365

I can see overclocking it a bit with a lower multiplier. At 15x with a proc speed of 3.3 and a fsb of 220 I get an overclock of about 14 (its at 414 I think). What I read was a guy with my exact ram raised the voltage to 2.1 and set the timings to 4-4-4-12. But you are saying a higher overclock would be better than tighter timings?
post #95 of 127
Ok I see that newegg rates them at 1.9v. I suggest that you leave them at 1.9 and see if they will go higher in frequency. If they become unstable before your cpu is back at 3.3Ghz, then go back to the 15x multi and see if you can change the timings. Basically you want to get the cpu as high as possible first, then squeeze as much out as you can from the ram without losing cpu performance.

Check the SPD tab in cpuz and it should list what timings it is rated for at specific frequencies. I don't know all the specifics as to which is better (timings vs. frequency). From what I've read and what I've been told, I'm under the impression that it is task specific and that there isn't an easy way to figure out which is best. Usually people will run multiple benchmarks testing timings vs frequency and choose the best combination.

I didn't know overclocking was so much work!

lol It really isn't that much work after you've done it once or twice. The hardest part is learning it the first time. After that it's a breeze. And you'd be surprised at how helping others helps you learn it yourself. When I was learning it I found it to be a lot of work as well... but after helping others OC, it has really shown me how easy it is.

You've done a great job OC'ing so far, keep up the good work

I tried doing a prime95 test at 3.3ghz and it errored out after a minute. I used the large test that tests the ram. I assume it must be the ram causing issues because the small cpu test was fine after an hour. Should I up the voltage on my ram?
post #99 of 127
Yeah you could try it. What is your ram currently at? I know newegg lists your ram for 1.9v, which is lower than most ddr2-800 ram I look at (2.2v). But then again, your ram is 2gb/stick so maybe that makes a difference. Look around and see if you can find a post on your specific ram. If you can't, then you may want to make your own thread about it and see what people say for voltage.

I'm running the same ram as you, but the 2gig kit instead of the 4 gig. I've had them at 2.25v and DDR1000 stable... last night I ran orthos for an hour with them at DDR950 speeds with 2.05v. One of the issues with ram and the voltage increase is heat... these XMS have some pretty sweet heatsinks on them, so you should be fine with up to around 2.2-2.3 vdimm.
