Finally stable at 4.0

post #1 of 6
Thread Starter 
For a year I could not get past 3.8 ghz without BSODing or restarting. It was really frustrating. Well gigabyte had an updated bios (F12). So I updated and tried again. After playing around with the settings, it seems like I have a stable configuration at 4.01 ghz on air cooling. I am running Prime95 in Blend and I have been stable for 8 and a half hours. I will run it for a few more hours then declare it stable.



After I establish that this configuration is stable and I can fall back to it if necessary, I am going to try to lower Vcore (1.40) to see if I can run a bit cooler... I have no problem with these temps though.

Lucky, I barley got my 930 stable at 4Ghz.

Yeah. It was really frustrating because no matter what I did I would crash. So I left it at 3.8. I saw that gigabyte had a bios update so I flashed it and then tried again. What seemed to finally work was setting my command rate to 2T, uncore to 2n+2, qpi ratio to auto, and add a bit to qpi voltage.

I lowered my vcore from 1.4 to 1.3. Lowered my temps by 10*C my high temp is 73 (usually 70-72 on my hottest core) on Blend. If this is stable I will try 1.25. If I am stable enough I may try 4.2 ghz.

The odd BCLK/multiplier value seems to be more stable. I will stick to that.

Stick to 21x multi and after 4.0 the chip starts needing a lot of vcore. So don't expect it to run 4.2 @ 1.3vcore if your 4.0 is 1.25. Like with my 930, it takes 1.2 for 4.0 and 1.39 for 4.4. It starts taking a lot, but so far good overclocking. I usually try my highest stable overclock with stock vcore then bump up until unstable and then increase vcore then do it again.

I am 11 hours stable on Blend at 1.30v. So this is now my new baseline stable I can fall back on.

Gonna do bring it down to 1.25 and see. I ended up going backwards because I was used to this thing failing to do anything above 3.8, but it seemed like the BIOS flash update rectified it. When Gigabyte described the update as "improved memory management," I knew I had to give it a try. I seemed to have found a BCLK/multiplier that this system likes. Let's see how low can I go with this D0 CPU.
