Quick first impressions of the 990x
After bios boot time is 3 or 4 seconds with twin ssd corsais HP3s in raid0 (I know!)
Temps are stupid low in cores never hits 20c
games look so good it just plain ignorant.
4.3 so far with HT and
Well after spending some time with this board I can say two things. One, Newegg apparently went ahead and shipped the Intel board, surprisingly enough it has been a pleasure to use so far. Two, this CPU is just.... wow. I don't know much about QPI overclocking in general and I've only educated guesses on voltages based on my experience in the past. Regardless of this guesswork I am thinking that 4.3 is pretty good. Oh and did I mention my voltage, 1.26. HT is on, all the energy saving is on, turbo is off, (at least until I'm finished violating this beautiful little flower anyway
In short this thing blows me the hell away, I can play mass effect 2 with absolutely everything maxed including x8 super sample morphologic AA. x16 still stutters a little. Now I have also realized that my cpu was not holding back my graphics card before. In fact it was basically the board I was using. It was an outstanding board, a flagship DFI model, but memory speeds and the lack of 2 full x16 pcie slots were simply holding this card back. My HD 5870 now screams at 100% like it never did before. In short I am blown the hell away with my performance.
Did I mention my temps? Just plain ridiculous. Last night during a quick stress test I never saw even 20c on any given core. This could be wrong as this board demonstrates some obvious bugs when reading temps (ie. Northbridge @ -232c???). I did the old touch check just to be sure I wasn't cooking anything... Even the damn water block stayed cool to the touch!!!
Now for some problems I am having. First of all, stability, while not fully stressed yet, seems rock solid at this point, Running oblivion with the absolutely everything visible mod is a nice quick stresser btw and doesn't flinch. The wierd thing is even a single mhz at this point cripples my stability and hardly loads OS? How can such a small change at this point so radically effect stability? Another thing is that my memory is rated to run forever at 2400. I am not able to get near this as it seems to putter out around 1800. The site calls for 1.66 volts for the DRAM, but the board gets all pissy when at this voltage and fails sever posts. This may be because 12 gigs of RAM is kinda retarded for overclocking, but this sucker has to be my home webserver soon and I need the footprint for multitasking. That and I'm an ass that wants to have his cake, eat it, throw pieces of it at my guest, and finish with some sodomy. In other words Im a high maintenence user.
Things I have tried to get past 4.30
Tried upping v-core by as much as 1.40... no change
Tried upper QPI volts to 1.25 from 1.1 and I have gone higher, no change.
Tried disableing all energy saving features, very oddly... no change.
Tried lowering my QPI strap to loosen up mem a little, again no improvenment.
I tried raising my mem volts, but the board hates this.
I have not used a QPI based board before now so any pointers are appreciated, also safe temps and v-core for this sucker if anyone knows.
Ps thinking now about gtx580s as my HD5870s are not nearly pushing this monster, so why not open it up all the way? Any recommendations of HD6970s vs GTX580s would be just awesome.
Also any help on the QPI strap and what it affects would be splendidEdited by NonOtherThenI - 2/23/11 at 9:13am
