[Gigabyte DSH4] OC Issue w/ 6400+ / PC2-8500

post #1 of 8
Thread Starter 
I have a GA-MA790GP-DS4H with a 6400+ with 4gigs of KHX8500D2K4/4G, Now I only have DRR2 800 MB, but my ram can run at 1066MHz. so if I OC my MB with a FSB of 290 @ 11x it would put me at -10MHz on my CPU and 1063Mhz for my ram.. but.. I wont post or pass post. I turned up my voltage on my ram to 2.2 in stead of the regular 1.8. I shouldn't have a issue here correct? My FSB goes all the way to 338.

Any Ideas.. Thanks

Have you tried bumping up the SB voltage? the SB can get voltage hungry after about 250 fsb, so that might be what is actually holding you back right now.

Give that a shot, and see how that goes.

Good luck

I have found it was the timings.. at 800MHz with 1.8v it is 5-5-5-18, I had to change the timing to 5-5-5-15 at 1066 with 2.2v.

Issue #2,

My 3dMark06 Pro Scores are low.. I will post more data here soon and you can see what I mean.

Glad you got everything worked out, although I'm surprised that things became more stable as you tightened the timings.

Interesting that your scores went down... but i guess I'll wait and see what you mean, before I worry about it to much.

Good luck

Okay well here it is..

Standard.xls is the Excel Output file for 3DMark06 (Stock Settings)
OverClocked.xls is the Excel Output file for 3DMark06 (OverClocked)
Hmmm.jpg is the Output data Mixed with change.

As you will be able to see it is not much of a change, with such a huge change in speeds.

Interesting indeed. your OC is about 10% but you only see about a 6-8% improvement in benches. In all reality, I personally dont think its that much of a deal. And I'm not familiar enough with those tests to be able to tell you why the scores are like that.

The only thing that I think might be happening, is that the PSU isn't up to powering everything after the OC, so its being limited that way. Do you have a link to the PSU you're using? It would be interesting to see how much amperage it has on it, although it is an antec, so its probably fine.

Good luck
