EH wait..... convert to RM + shipping how much?

Still 60-65% of price here.

hey guys just curious I am starve for single threaded or 2 threaded performance but I am not willing to go higher TDP for my 2500K since the performance of all 4 cores @ 3.3GHz is more than enough to feed my need, so I am sticking 4 cores @ 3.3, but OC in 1-2 core.

Can I leave anything to auto and just adjust the turbo for single and 2 core, even Vcore as auto, how is the vcore in Sandy work? will it increase if I leave it auto when I just adjust the turbo 1 active core @ 4.2Ghz/ dual core ~4GHz? because as far I as know most Sandy can run fair well <4.2GHz @ stock volt.

because previously on socket 775, if I leave it auto the Vcore will increase itself when I OC despite I stay within Stock voltage OC range.

System spec
Intel 2500K
Asus P67 Sabertooth B3
2x4GB Corsair Vengence 1600Mhz CL8 kit
Leaktek GTX570
80GB HDD + 1TB HDD
Xigmatek NRP-MC651 650W PSU

EDIT: besides Any idea how/what application to stress test individual cores? (single core/dual core/triple cores).

hey guys~
if my rig can run 10 intel burn test in (stress level - maximum) without any problem~ does it means stable???
cos i hv no time to run p95 for 24 hours~

Most SB can do 4.2GHz at stock vcore. afaik In bios u can choose all cores to run at 42X multi hence overwriting the turbo function. i believe the bios can auto adjust the vcore for u nicely. monitor the vcore in windows by tools like realtemp, coretemp, aida etc... IBT/LinX can choose how many threads to stress. otherwise, u may as well disable the core & thread in bios.

hard to say as lots of ppl said they will still get BSOD even though IBT/LinX passed.

how about now?? hv been running p95 for 8+hours~ now error~

there's no best stress test... error could be bad mem settings etc as well.
when troubleshooting problem like this a screenshot as a proof is required. i don't trust typing lol.

OH SO SRY!!!!!
typo!! now = no problem~ sry~

from my little experience, oc memory will give u bsod most of the time. So, it is better to stick to ori frequency for long run. So far i didnt face any BSOD on cpu ocing.

+1
must know some rules applied on mem OC. eg.
tFAW must be at least 4*tRRD
tRAS = tCL + tRCD + tRP, not necessary but highly recommended

4.6GHz at 1.37v, not stable. Keep getting x101 error.

Yeah I think I got a shit chip. I'll just settle with 4.2GHz. :\

4.6 i think u need i.4v.

It is stable on 1.4 but I've been reading everywhere that people have been running 4.6GHz on 1.35-1.37v.

thanks for replying, so if I leave Vcore at auto will it go over the Intel spec? because as far as I know if it clock higher the Vcore go up as well.

Its not that I fear it will break on overvolt, since I do rather mild OC only, but more like I want power consumption stay max 95w only.

CPU Current Capability = 100% I leave it at 100% whats this thing?

I got aida64, and manage to use its build-in stress test each core, 2 core or 3 core.

My Report
So far I only got turbo in these frequency without itself clocking back down, because if I go higher it will quickly clock back down after I stress a while.

1. 4GHz turbo when 1 core active.
2. 3.6GHz when 2 cores active.
3. 3.5GHz when 3 cores active.
4. 3.4Ghz when 4 cores active.

seems the turbo function are rather poor, if keep clocking down if I set too high.

Cooler is Hyper 212+ in a non air-cond room at 31c afternoon.

When you put settings on auto bios will control vCore behaviour based on the speed you set.
High or low is depends on mobo bios. Don't take too much about Intel specs as the actually vCore read by DMM doesn't really tally with what you see in bios/software.

CPU Current Capability: Increases the power threshold before over-current protection limits power (either by shut-off or throttling). If low OC just leave it auto.

Thanks again, I guess I need to manually set my Vcore instead of letting it auto to keep my TDP under control.

first thing is to find the VID for the chip @ 3.3GHz.

you getting x101 error? Look 4.2GHz is more stable oOoo

I've put a spoiler on the 2nd fan of the heatsink so that some air is directed to the VRM below and voila i've got 122GFlops on 4.5GHz.Looks like it really did overheat.Thanks for your help.
