further 980x adventures

[Shmee]

So, I couldn't sleep very well, so I decided to get up and adjust my OC. It is an ES 980x B1 on a UD5. I had it before at 133x32, at 1.43 Vcore. By reducing the multi to 25, the vcore to 1.41, and upping BLCK to 172 and QPI VTT to 1.295, the memory ratio from 10 to 8, and increasing uncore speed to 172x19=3268 MHz, I will be getting better performance, (higher bclk and uncore) with less vcore. I have not thoroughly tested for stability yet, but I have done a few passes of linx and so far so good. Good enough for tonight at least. Temps were averaging mid 50's max.

Before I went any further, (I plan for 4.4 and faster uncore) I just want to make sure that I am fine as far as voltages. Under 1.3 VTT is fine, I assume? And I plan on staying under 1.45 vcore.

Finally, I wonder if my current luck has to do with using an odd multi, or simply I was able to Decrease Vcore by increasing VTT, or both?

Benchmarks of this and 5870 tommorow.

I would be careful of VTT or VCORE > 1.4V at 24/7 load particularly on ES B1 chips. They are higher leakage than retail and jacking up VCORE does help them clock better but many have also reported sudden failure too!

Depending on your board you may have more options such as IOH/CPU PLL voltage (which if it can be set LOWER than 1.8V can help significantly!) etc.

Interesting. I just set those 2 to normal. Actually, I believe I bumped IOH by .01V. I heard it helps with higher BCLK.

Anyways, I dont plan on going higher than 1.35 VTT (the pink zone) or much more vcore either.

On a side note, will any news on the 8 core 32nm chips coming up? I saw a brief article on them, and was wondering if an ES from that series might work in a desktop board like my UD5

TY as always for advice.

 

[Rubycon]

Yes 8 core 32nm - need those badly!

45 is too hot!

4.4GHz uncore? Let me know how that goes.

4.4GHz uncore? Let me know how that goes.

no no. 4.4 GHz core clock, MB 3.8 uncore. Mb a bit less.
