2600k @ 4.2 + 16GB ram

post #1 of 24
Thread Starter 
Hi there. My problem: Can't get 4.2 to work stable on 2600K.

So far the best I had is 4.2 Ghz set with 1.255v. Went for about 20 minutes in prime95, then BSOD.
Wanted 4.4 Ghz but no luck. Maximum was like 3-4 minutes in blend mode.
anything changed in voltage higher or lower crashes the system in a few minutes of prime95 blend test.

What seems to be the problem I think its the 4 sticks of 4gb each ram (16 GB in total).
Now i have set it to:
1600mhz 1.65v 9-9-9-24 (this is the stock).
Do I need to alter anything in ram settings in order to successfully OC my cpu?

p.s.: temps are fine. got aftermarket cooler. after 15 mins in prime95 stays in stable 58-60 c.
My system:
i7 2600K
asrock p67 pro3
4x4gb patriot G2 1600mhz ddr3

Thank you in advance.

No you leave the ram on sandys. Even on my 1336 I oc to get the ram at a stock speed,

1 stick of ram is easiest to overclock. 2 sticks and the mobo should be able to handle it. 4 sticks and if it's crashing, try setting your ram to specifications manually, and up your VTT voltage to at least 1.1, maybe 1.2 (which intel says is the max). you can also verify if this helps by taking 2 sticks out and trying your same blend.

More RAM you have, it gets harder to OC.
And it needs extra vcore just to handle that 16GB.
Also I'm pretty sure it needs more vtt(vccio) and dram even at stock.
At 4.8, with my 8GB ram, even set at stock, I need to bump up vtt and dram to make it stable.
Since you have 16GB it'll be hard on the IMC.

I have the same type and quantity of memory and I needed to increase Vcore, VCCIO, and slightly overvolt the memory to 1.664V to have the system run stable.

I'm running 16gb at stock and at 4.8ghz stable I've seen my dram drop to 1.488v during blend runs or just sitting idle and jump to 1.515v is this normal? Most of the time it is fixed at 1.501v. I wonder if upping my vccsa/io and/or ddr voltage might allow me to drop my vcore a tad?

This^, try increasing VCCIO to 1.15v

Ok so now I managed to get something better, but still...

Now the settings are:

Cpu ratio: 42
turbo boost power limit: Manual
Short duration power limit: 270 (i dont know what to set here)
Long duration power limit: 220 (this either)
Long duration maintained: 1 (and this either)
core current limit : 200 (and this...)

ram settings set manually to manufacture defaults.
Vcore: 1.255 (raising to 1.270 PC restarst itself after 1 hour in prime95)
dram voltage: 1.665
vtt voltage: 1.159
vccsa: left in auto

So this is the best I have so far... after 2 hours prime95 crashed, though Windows was still on and working.

What else can I tune to work this out? Do I raise vtt?

Thanks guys for your help

It might not like the combination of your ram and other components.
Either CPU or mobo....
Since SB likes 1.5v ram. and you have 1.65v and 16GB of them.
Have you tried with 8GB of ram with same settings?
If that passes then it's not liking the 1.65v 16GB ram.

I think it should be fine with 8GB like Tunagoblin suggested. I never had a problem with this RAM until I got another 8GB, and that was before I understood that 1.65V was better suited for Nehalem than Sandy Bridge. I've had to run VCCIO/VTT ridiculously high beyond anybody's reasonable recommendations to get 16GB of 1.65V to behave at 1600MHz speeds. I've now downclocked to a stable 1333MHz and am going to buy lower voltage memory instead. I've concluded that the high voltages aren't worth the trouble, especially not on this Patriot G2 RAM which I've determined isn't that great for overclocking anyway.
