The Prime95 test still rockets my temps up pretty fast, but hopefully with a bit more tweaking, I can get that under control too.
Quick question to see if I'm grasping what you've posted so far -- When working to overclock my system, I want the highest possible CPU frequency coupled with the lowest possible Vcore and VTT voltages that will result in a stable system, correct? Is this because higher voltages contribute directly to more heat?
On a tangent now, I know we haven't talked about RAM here, but I noticed your membory is running at 8-8-8-24. Mine (on auto settings) is 11-11-11-29, but from what I've read, lower numbers are better there, right? When I tried to manually set the memory to 8-8-8-24, I get a BSOD during bootup every time. Is it worth worrying about that?
It's better to mess with the multi other than the bclock alone.
The reason for this is that the bclock is used to control the speed of many components on your motherboard, no just your CPU. RAM, for example.
The thing is, messing with those components can be hard, and you will not really get a big difference in term of performance.
For example, a 200mhz in ram is HARD to get, with good timmings. but that will only give you a 0.5 FPS in a few games. People who overclock RAM are those looking for the maximun performance, like benchmarkers, looking to rip 0.1 second of their superpi time to win a torunament
So YES, it's better to mess with the multi. Since you have a more expensive K processor, which means it has an unlocked multi, mess with it.
My chip can only go up to 20multi. The normal 870 can go to x22, and yours is the same as the 870, but with that multi unlocked.
btw, I forgot to mention about the pci-e clock you asked me yesterday (I was sleepy like a zombie) Well, want my advice? Don't mess with it!
It will not magically overclock your pci-e cards giving a performance boost (that's the first thing we think of whem we see it) but others also meantion that it can improve stability, like you mentioned from the guide.
The thing is... pci-e clock is kinda mistical... people say complely different things about it, and nobody seems to show proof. like it can damage your system, can make or not your system more stable, etc.
What I KNOW is... it doesn't really give you enought performance to justify mesing with it (just like RAM) and yes, it can make your system more stable, but that's on an extreme overclock, which is not our case... so just leave it at 100mhz.
Btw, it's so messy because it control many things in your mobo, not just pci-e video card related stuff, but some stuff related to the SB, like sata HDDs
for your question about voltage X heat: YES you are correct.
basic physics: U = R.i
So if you increase the voltage you will also increase resistance (more heat out of the processor) as well as the power (more stability)
btw... the "problem" with heat is that (specially on AMD CPUs and GPUs) is that the more heat, the worse it will conduct electricity, which means more instability. I said this is a problem for the erveryday user.. but for those extreme OCers this is great, sicne they keeo the processor under 0C
but yes... you are correct. maybe I told you to start with too high values on those tests - 1.4v for my processor, maybe you should lower it to 1.35v or 1.3v at first....
btw, intel states 72C for our processors as safe temps...
intel burn test/ linx are the programs that will generate more heat.
so read it like this:
85C on linx = 77C on prime95 blend = 72C maximum
temp on normal usage ---- those values are not accurate, obviously.. it's just for you to have an idea..
so when testing, don't really mind going to 85C or 90C at MOST - cancell you tests and lower your voltages if temps are raising that high
and again, that's the beauty of overclocking.. the highest clock, with the lowest voltages and so the lowest temps.
my system is stable at 1.4v but it only need 1.35v... that's the beauty of overclocking
well.. I think I have answered you RAM question previously...
just think about all those timming numbers.. you've got to mess with all of them to make it stable... too many variables! just leave it at stock settings (no auto, try to manually set them to stock settings) loose them a little if you need - for example, if they are meant to be 8-8-8-8, leave them at 9-9-9-9
maybe you should mess with the T value (forgot the name) but it's the one that can be 1T or 2T
that can help a lot on instability - but you might not need to mess with it, if you OC only with your multi, that will change only the CPU clock and leave RAM and other components stable as stock settings!
