i7 3820 - 4820 Overclock Club - Page 266

post #2651 of 6500
Has anyone OC'ed the 3820 with a GIGABYTE GA-X79-UP4? I am not looking to find the limit, more hoping to get to about 4.3Ghz or thereabouts, but on air, and for it to be rock-solid stable.

LayerC, have u thought about throwing in an additional very small and very low drag rad in between the GPU and CPU blocks to give it a little lower temps going in?

I wouldn't worry unless your pushing into the high 80's or 90C range.

When I've got the system under full load im hitting 90. That's gpu's + cpu

You could run 4.3 on stock voltage, just raise the multi.

Thanks Tsm, I thought I read that on some other thread, so I am glad to hear that again on this thread. That is what I think I might clock it at for a while (unless higher is safe and easy... is that a possibility?), just till I upgrade my cooling at least a bit. And what would you say is the ceiling in terms of clock for air cooling?

And what is the chip's temperature threshold? What are we looking to stay under? edit: I mean, as I am sure all of you know a 66.8C Tcase spec given by intel, which is is pretty low, could I expect to stay under this on air at 4.3Ghz

(just looking for rough estimates thus far so hope u guys don't mind the basic and general questions)

This is an early cpu overclock test. For longterm stability add around .03v to each step. Over 4.8ghz things start to get toasty outpacing a DH14.

4.3 = 1.22v
4.6 = 1.3v
4.75=1.345v
4.87=1.4v
5.0=1.45v
5.1=1.51v

Great info for where I'm at in terms of very preliminary research. Thanks!

So with Intel themselves specin' their VID up to 1.350V, it seems it really becomes a matter of cooling alone for a long stretch before getting to the top end where you guys are pushing them... From the sounds of it I guess I should be able to set it to about 4.3Ghz or so without even needing to think about getting anything new for cooling at all......

And it sounds like I could get it much higher with something as simple as one of those plug-and-play water rad systems while still retaining rock-solid stability... I mean, cause with those numbers you guys are throwing around right now it sounds like I could set it to rock-stable 4.75Ghz with something as simple as that Corsair plug-n-play H80i.... (which is very decently priced, and not so bad and toy-like anymore, I mean it would be nothing to be proud of, but that should be way better than an air even with a good air-flow case)... giving me 10% more speed and at the same time adding to temp safety, which I want

Am I way off?

OC and cooling asumptions aside, does anyone know of a good OCer MoBo that will let you run 8x 8x 8x 8x?

I was looking at the Gigabyte GA-X79-UP4 till I saw this review on the egg...

the only board ( i think ) asrock extreme 11

edit: i thought you said 16x the extreme 11 does 16x 16x 16x 16x
I should game.

No, UD7 and Assassin2 also do quad x16

The RIVE, and RIVF will do x16/x8/x8/x8. The ASUS WS will do Quad 8's
