Haswell Overclocking Guide [With Statistics] - Page 576

post #5751 of 19540
haha, sorry guys - getting sleepy and thus getting sloppy tongue.gif

---
It was a STOP error during the x264 run. Attached below you can see I've been dealing with mostly the same error all day. The newest dump file is the one I referenced above (the 4.4ghz @ 1.28VID / 1.30Vcore run). Below that new dump file you'll see some attempts to get other frequencies stable @ various voltages, ram timings etc.

Screengrab (Click to show)

This x264 run was done at:

Frequency: 4.4
Uncore: 3.5
Vring: Auto (UEFI suggests it's hovering around 1.14v, but that's at the UEFI so I'm guessing it's higher once I load the CPU)
VRIN/VCCIN: Auto (says 1.78v at the UEFI, but as above...^).

I'm assuming the VRIN/VCCIN value I pulled is correct - it's the highest value I can see listed in the voltages area of the UEFI (the lables in the Asus TUF UEFI aren't completely consistent with the ROG UEFI lables).
Let me know if you'd like any more info and if you would prefer me to make a thread elsewhere as to keep this thread cleaner thumb.gif

^You're getting tons of 124's.. Manually set uncore to 34x, not 35x, manually set vring to 1.2 and then manually set vrin to 1.85 or 1.9 with a high level of LLC

i know what you mean ,but my mobo apply the Unicode voltage in steps...so 1,18 means prime can pull maximum 1,2v avg. 1,192v with 1,185v maximum 1,208v avg 1,2v (all voltages under prime in daily usw @ the set voltage

CPU/MOBO - i5 4670k (Malay)/Asrock Z87 Killer
CPU Multipler - 43
Cache Multiplier - Auto(so 43)
VCore - 1.23(Adaptive with 0.030)
VRing - +0.001(offset)(My mobo matches the Vring == Vcore mostly)(I have to set manually if i dont choose adaptive for VRing).
Vinput - 1.9000v
Max temp - 72c(Cooler master hyper 212x)
Stress - Intel burn test/3dmark.
Power supply - VX550w
GPU - R9 280x


This is the safest overclock i found for this.
I can boot to windows until 4.6, but i could not stabilize the CPU at 44 with 1.3v.
I tried to gain extra headroom using cache mult at 34 but it didnt help.
I am afraid to go over 1.3v, since i have also oced GPU to 1100/1600

I have the standard Corsair ram at 1333mhz at 1.5v.(Does changing ram to a better quality, help with OC?)

No it doesn't, it's just read that way in software, which is an imprecise and inaccurate reading wink.gif

^I'd suggest set uncore to 34x, manual ring to 1.2 just to be safe, and keep crashes clear. Put VRIN LLC on near-max level, and also try increasing it, etc at 1.25vcore, use 1.85vrin, at 1.3vcore, use 1.92vrin or something like that etc. You could try using x264 to stress, see what happens there. Linpack (IBT) without avx isn't a great stability test, and with AVX is very hot and punishing on some areas of OC but not others.

Don't use adaptive volts til you're 100% stable, IMO.

And most important thing: Bluescreen codes? Even with them, you're looking for needles in haystack for Haswell stability sometimes, without them.. there's not much to say.


Faster RAM makes OC harder, not easier. Better performance (especially like 2133-2666 at nice tight timings vs 1333 at like c8/c9..) in some cpu bound stuff, though

34x still needed for 4770k, yeah? I'll try setting vring and vrin to those values and report back. Not sure where to set LLC on this mobo, ill find it though
post #5757 of 19540
Yea it's confusing if 4570k etc has different uncore by default.. 35x is the value on my 4770k that turbo's, 34x does not

I am not sure if something is wrong with my Raystorm (going to try remounting it), but at 1.3 V vcore I am already hitting 85-92 C with Prime95 (small FFT, 2nd iteration of blend), while Intel XTU is more around 65-74 C. My cooler does have some light scratches on the copper, but thermal paste (MX-4) should make that a non-issue.

I stay around 60C after delid, CLU, h110 with 4x 140mm fans blasting (and 6 other fans in a basically open bench setting). It also helps to have 10C weather because I insulated my computer room from my house. In normal ~22C/70F room temp, I hit about 85C max though in p95 28.1.

Did you not delid? It's unclear if you are saying you delidded or not. You need to delid. A raystorm is at ~90C on 1.3v is something very wrong.

And I found your 'very wrong' biggrin.gif

Like, you paid $200 for a top of the line, modern cooling system. You pay ~$400 for a top of the line, bleeding edge new CPU. And then you pay... $2 for a 4 year old, crappy thermal paste lachen.gif

Get some CLU man, $12 on sidewinder. It'll easily account for a 15C drop over MX-4, which is just an awful thermal paste. You'll probably see more like 20-25C if you delidded, ~15c if just IHS. It's $12, and the best value you'll find in cooling anywhere. It just boggles my mind people spend so much on their system and completely neglect their thermal paste.

And no, there's very little difference in modern thermal pastes. But MX-4 is not modern anymore, you don't use DDR2 in a modern build either. And MX-4 was always mediocre. There's very little difference in modern pastes like PK-3, Masscool, Gelid, Hegrease, but MX-4 is crap. And CLU is an extreme TIM, not your average ceramique.

I mean the very least you could spend $9 on hegrease (best ceramique), or $3 for PK-3 or Masscool for 1.5g (enough to last a lifetime if used properly).

I try 1,185v uncore and if that crash...1,19v....because i m fully stable @ 1,2 ...and this is way mre than needed for daily use...i also thing that prime 28.1 is zur hardest test for uncore
