Issue with my 1090T

post #1 of 12
Thread Starter 
when i overclock my 1090T beyond 4.5ghz i have a weird voltage issue. I set the voltage to 1.55 in bios and in cpuz and hardware monitor it never stays there. whenever i launch F@H or linx the voltage drops to 1.4X then drops to 1.24vcore and my rig crashes OR downclocks to 4x muti for a few seconds then resumes back to 17x. i have CnQ disabled and the temps are never above 45c... any suggestions?

edit: the reason i want to run at 4.5+ is I'm a 24/7 folder and want more work units to be done, i don't care about PPD but i do care about the research being done

4.5 is a pretty hectic overclock! What board are you using? Do you have the latest bios and does the issue occur at lower clocks.

issue doesn't appear until >4.2ghz but it doesn't get bad until 4.5. I guess I'm just trying to chase my 965 clock at 4.8ghz folding stable and 5.1 benching stable... using an Asus M4A79XTD EVO

I had an odd issue with an asus board where when I used the reference clock to overclock the voltages would go out of whack so my only choice was to use the multi.

I would try a bios update first and maybe try messing with the boards LLC options if it has one.

I updated the bios and there doesn't seem to be any LLC options... currently at 4.08ghz

240fsb 17x multi and 3 days of folding stable thus far, max temp was 37c

Try pushing the multi higher and using less base clock. Though 4ghz on a 1090T will still push out a few units
