Can't confirm whether it's PSC chip or Hynix. If it's PSC should be fine, Hynix doesn't like SB.
IMO better avoid this Crucial. any RAM that's released before SB (January 2011) might have compatibility issues with SB. U might be able to power up the RAM but not at rated speed/timings/vdimm, or not post at all.
if u could find G.Skill RipjawsX, this is the best RAM for SB. in fact it is specially designed for SB.

Any idea to get which jaw x?
1.65v vs 1.5v


Added on January 5, 2012, 8:39 pm

Any idea which is best? Some link to the model?
Staying at jb, mostly get part at sg or online

Btw I plan to use wb on ram too, possible?
Corsair gt? Is good?
*
The best OC RipjawsX is the BBSE chip 2133 8-9-8 kit, but too bad 2x2GB only & hardly available in the market due to chip shortage.
Go for 2x4GB instead, grab the 2133 9-11-10 kit I believe u can find it in our garage sales.
1.65v or 1.5v doesn't matter as both will work just fine for SB.
JB u can go to danga city mall find hilmiangah.


Added on January 5, 2012, 9:07 pmto watercool RipjawsX, u must disassemble the heatspreader and get a Koolance ram cooler. for Corsair dominator, just grab the EK block.

Who selling?

Target to get 2x4g 1866-2133
G skill should be good too, lifetime warranty from sg local distro below 200sgd
Just got my p67 m4e
Now looking for i72600k or i7 2700k
Any seller to look for???
Pm clawhammer
He dun have stock already
Pp playing x79 now while I am on budget sad.gif
Wc burn money ...

yep that's the new Hynix. old Hynix won't work correctly on SB. either need higher vdimm or loosen timings.
no idea on micron but any RipjawsX will work perfectly at rated specs on SB.
PSC based DomGT 2000 8-9-8 1.65v v7.1 will do 2133 7-10-7-27 @ 1.65v, but still 2x2 kit only.
You might wanna search for DomGT & 2600K in LYN garage sales.

I haven't been to JB since 5 years ago but Tmn U Skudai there are many shops selling at student's price. Cytech, New Century Comp, X-Tech (IvoPC) etc to name a few but normally CPU price is standard everywhere so offering the same price. afaik forumer Dennos is using the same kit RipX 2133C11.

Thanks man

2133cl11 4x4g sgd 250
Was thinking to get either one
Do we really need 16g?
4 stick harder to oc?
Maybe hunt the chip tomorrow or Sunday smile.gif
Best at lowyat is 880, which I know...
Not sure jb got any price close with that ...
Thanks for the advice smile.gif

4 sticks are harder to OC. Don't really fully utilize the RAM the largest amount i've used before was 5.5g max. biggrin.gif
I'd grab the 2133c9 2x4gb kit, tighter timings & easier to OC.

I have a Maximus IV Gene Z68, i5 2500K, 2x 4GB 1333MHz Corsair Vengeance (9-9-9-9-24). Auto tuned to 4.4GHz with 1.38v, it's unstable. Tried with bios EZ profile at 4.6GHz with 1.35v, also unstable. Right now running at 4.2GHz but I have yet to stress test it (not at home right now).

What could be the problem of the unstable OC? I thought 1.35v is more than enough for those speed. During BSOD I recall reading somewhere about clock speed error.

Or could it just be my PSU? But it's a 750w Strider 80+ silver and I only have one HD6950 in the rig.
*
I think that's BSOD 0x101, which is related to insufficient vcore.
try bump up the vcore.

hi guys  smile.gif
At what level should i run IBT and LinX stress test in order to say my overclock is satisfactorily stable ?
Standard, High, Very High or maximum?

It seems i cant complete more than very high level (>4Gig Memory usage)...Its require extra voltage and produced more heat.... sweat.gif
*

maximus level is preferred coz it stresses the total amount of your usable memory, at the same time stressing your core clock & IMC to the max.
8GB should be taking an hour to complete 20 runs.
imagine 16GB is 2 hours lol.

The more ram amount u test the more efficient vcore u will find. Meanwhile the 2GB module is more difficult to OC than the 4GB. Latest games like Crysis2 etc will utilize lots of ram & this is where u might get BSOD etc due to inefficient vcore (means u set vcore lower than it actually needed).

bearly hear the fan spinning on my Corsair's.
ur PSU is running hot that's why it spins faster & louder.
could be due to overload & 24/7 folding.

Just had a quick OC run with my rig

i5 2500K 5.0 GHz  [1.45V Vcore in BIOS,Internal PLL Overvoltage Enabled]
MSI P67A-GD55
1X4GB Mushkin Value DDR3
CM 212 EVO Push/Pull

What do you guys think?Personally i'm having doubts at running my CPU using that much voltage sweat.gif

nice try
i think ur CPU speed is throttled down coz it hit 98C already. hmm.gif
looks like u're running on vanilla win7
expect higher vcore on win7 SP1
should run LinX on all the mem

aircooling won't be able to do IBT/LinX stable @ 5.0GHz

i'm back to 4.7GHz @ 1.30V in BIOS right now.About that run,i've already have SP1 installed .
One thing that's bugging me right now is that with LinX 0.64 [All RAM] i'm only getting around 94Gflops at 4.7GHz while i'm seeing people say that they can get 110Gflops~ at 4.5GHz.
What do you think would be the cause of this?Max temps are below 80c with this setting. hmm.gif

use the latest LinX/IBT posted in my post #1?
should be getting above 100 gflops

How to get 5.0ghz >.< what need to change (i mean other's from core volt)....  icon_question.gif  icon_question.gif  icon_question.gif

other than enabling internal CPU PLL overvolting & increasing vcore, i don't see any other settings to change.
i see u got a bad chip, might wanna try 1.55v @ LLC 75% or 1.5v @ LLC 100% (watercooling only)

I've tried with the Linx you posted on the first page and still i'm only getting around 98Gflops only. rclxub.gif

don't know what's the reason behind this but that low GFlops means CPU throttling/ underperformed. could be VRM overheating
turn off all power saving features C1E, C3. C6, EIST
windows power management set to high performance
in LinX set priority to above normal/real time, run all mem
or could be other OC settings failed to work

QUOTE(hahariz @ Jan 30 2012, 05:22 PM)
Finally have the time to test my OC. Went for 4.2GHz on 1.3v, still not stable. Now running Prime95 with 4.6GHz on 1.4v, I hope it's stable. :s

Off topic; does expensive thermal paste are actually better? Any good thermal paste for recommendation?

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).
*

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.

hey guys~
if my rig can run 10 intel burn test in (stress level - maximum) without any problem~ does it means stable???

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

there's no best stress test... error could be bad mem settings etc as well.

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.

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

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  biggrin.gif
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.
