Thanks.

Yep. Well I use it as a stability test in itself. Coupled with my gpu miner, that is the absolute max heat output my PC will have, so if it's stable then it should be stable all the time. Right now im at 48X, 1.475 VCORE, 1.9 VCCIN. Ram at profile 1 (2400 10-12-12-34), uncore at stock

Great, someone I can relate to! tongue.gif

I am also using MinerD to stress test, as it can flip instability within 10 minutes, while Prie95 can rip through 30 minutes of a Blend test, have no instability, but....

44x @ manual 1.319v/1.320v. (Seen as 1.328v).
XMP profile for timings (mhz dropped to 1600mhz for sake of testing).
P95 Blend stress test.
No LLC set. VCIN at 34x (stock instead of auto). VRIN at 2.0v.
Passed 30mins worth of testing. Failed in temperature.

It's hitting 93c at times doing that test, so I am really not comfortable with this kind of heat profile. I am just on an h100i, not a nice custom loop like you, also my 4670k is not de-lidded. MinerD isn't getting very hot though, so what do you think I should do at this point? MinerD has been running 10+ hours now without a BSOD, still at 44x, 1.32vcore, 2.0 vrin/vccin, uncore at 34x (4670k stock rate), LLC 8 (highest), and RAM at 1600mhz with recommended timings.

Temps are acceptable like I said somewhere in the mid 60's at 1.36 so I'm happy. I might give it a bit more since x264 and my display drivers have failed twice already and I don't know if its the OC itself.

Again, no offense to the OP, but in my experience VCCIN has has little to no effect on my stability.

It depends chip to chip, mine will NOT take the vcore required for 47x (~1.36-1.37 load for solid) with 1.9vrin + extreme llc, and i saw a few crashes at 1.95 - i have a list of probably thirty 0x0101's from trying to stabilize it without knowing to raise VRIN back when stuff was less understood

Running MinerD CPU Crypto Mining for 8+ hours now! Previously, before setting VRIN to 2.0v (had it at 1.7v or so if you recall), and not touching the VCIN/CACHE, I had max 1 hour of stability running this.

Any suggestions of what I should do next? Maybe keep the 2.0 VRIN but put VCIN/CACHE back to Auto? I kind of made both of those changes at the same time...

Can clock up cache/uncore to what you can do with like ~1.15-1.25 ring or so! Maybe even a little higher if you feel like it and temps are acceptable (because adding another ~0.05-0.08vcore for 100mhz might be undesirable though probably faster performing option)

Sin's guide is a good quick reference, but it was made like a week after launch and not updated. This is more of a community resource thread with discussions, debate and edit rather than a static guide - there's plenty of them out there, though most are not ideal, are missing details, or are flat out wrong on some stuff

You could try setting pci-e to gen2. You have an nvidia card? It's been really dodgy on the driver side for quite some time, though with gen2 pci-e i've not seen it actually fail x264 (just a few restart loops into hard locks, as well as soft driver crashes.. which bring down whatever game you are running and also geforce experience if you are using shadowplay at the time)

Nice, those are some good numbers. If you wanted to take it one step further, I would look into some RAM OC'ing. Take it one step past that and I would de-lid.

Honestly, I knew I was going to de-lid before I got haswell, but was so nervous. Once I got it, my loop could keep it at 4.7ghz and it would top around 94C. But even now that I de-lid, temps are crazy low, but I am only at 48x so it almost wasn't worth it in my case. But in yours, you could gain way more.

Edit: Are you concerned that isn't stable? If so try the x264 benchmark as most here will tell you it's the best stability test. I myself prefer the miner or BF4. Also, you could try to move up that UNCORE. It will net you better scores in some benchmarks and/or help/hurt stability.

Well I personally don't think my chip is rather strong, and that is why I couldn't just get 45x with some more voltage /only/. So was curious what additionally steps I should take in additional tweaks. My ram is at it's recommended timings, should I put it up to 1866 instead of 1600?
post #8387 of 19599
Hey Bond I also with no offense to this threads guide followed SINS guide , and in fact talk to him quite a bit. My understanding per his guide which I followed was to set SA voltage to 0.15+ and others digital and analog to auto. I kind of combined these guides as a template. I've set my SA to 0.10+, and others to auto. I'm being told to set System agent back to auto, but I don't necessarily think I should. Am I causing unnecessary heat or degradation by keep SA to 0.10+ ? Point is I set my ram from rated speeds of 1866 mhz back down to 1600 mhz. This is the reason i'm asking about SA. My chip sucks by the way and am only at 4.2 ghz. I'm following SINS guide because I have a ud3h. He really knows gigabyte well.

What RAM is it? You will likely be able to get it faster

You know, I tried that too but never had any positive results. May revisit that again if I tinker with my ram. One would ASSUME that the increased (although small) SA, IA, IO voltages would mean more heat, but i'm not 100% sure.

If you're sure your ram can/will run at faster speed and timings, yet you still aren't stable, I would def try the +0.1 to each and see if it helps.

Actually, I believe System Agent voltage only really pertains to BASE CLOCK OC, so if you're like me just using the multi, just leave it at stock.

I basically above have the same issue, my chip really sucks.

Yeah I get that , but my issue really isn't an issue, what I meant was I don't see any real world heat difference like raised temps with my 0.10 +, what I'm asking is do you think i'm harming anything by leaving it alone at 0.10 +? I can simply turn it back to auto but if I don't have to why bother since i'm not really seeing any heat or stability issues in fact its stable, if I turn it back it may not be because my chip sucks, that was my point. Am I harming anything by leaving it to 0.10+ and not back to auto ?
