Thread: i7: And so it begins!! Well....That was easy.

Primed for an hour without any problems, so decided that was good enough to drop a bit more. Down to 1.26875v in the bios and started Prime with small ffts as usual. BUT it failed within just a couple of minutes. Guess I found the lowest voltage.. So will go back to priming with 1.275v in the bios. Either way, looks like I'm about to wrap it up with this CPU and call it a day. At least until my second 5870 arrives later in the week and I...

Reran Spi32m today matt. Actually got 6 seconds worse then the time I posted above despite running at what CPUz reports as 4.68 GHz. (If 22x multi was really effective I was at 222x22 affinity set to core0) just south of 1800 7-7-7-21-1T on the mem. Going to swap out and do some clocking then go back look at the architecture again and figure out why I am having trouble over 4.6 HTT (cant get 4.7 no HTT ) Common sense says it is the 222BCLK...

Very nice clocks matt Are you at 21x200 or 210x20? Also, whats your ambient temps?

While there is an available modified BIOS that removes all throttling, it is not officially supported by ASUS. Unless you're running that BIOS, then your board will at some point throttle. Good to hear that you're not encountering anything so far, it'd be cool if you go even further with it. Just in case, though, keep i7 Turbo running for as long as you're stability testing.

I'm comfortable with load temps up to about 80c, but that would be about it for me. At that point, as you said Neb, the 100-200Mhz gain just isn't worth it. Yeah, figured as much. At least your D0 is a cherry chip that uses alot less voltage to get the 4.0Ghz as...

I would not recommend going any smaller than 80GB. It's just enough even to feel comfortable. I feel for those who have 30GB drives, even two in raid 0, it's just not enough space. Good to know , as an SSD is next on my list Thx Matt

You may be able to shave a few more degrees of by setting the QPI voltage, to keep it from fluctuating. I use "about" 1.25V at x18, for x16 you can drop it right down to 1.15V

Well hell, you've got another 20-30*c to play with, give it 1.3 and see if it'll do 4.5ghz :P

Nice going Matt, the 920 on an average X58 board or better is IMO still the best platform to be on, with low temps, 8 threads and tri channle RAM you cannot go wrong Oh, and when the i9 beast sticks its big head out you can just pop it onto your current board. X58 platform FTW !!

From what Ive seen, alot of i7 that will run 4ghz under 1.3v will do 4.2-4.4ghz relatively easy on good voltage (under 1.4). And alot more will scale HORRIBLY after 4.4ghz and sometimes tough to stabalize for 24/7 use. Im not saying it doesnt happen, but i7s scalability after around 4.3 is not really good unless you have a cherry chip (and board...
