sup3rfly, those two list are very unorganized and very hard to read.
Plus, for the Corsair area, it doesn't state all revision of XMS rams. sweat.gif

Useful links. I suggest putting these on the first page for easy references.

If not, difficult to find later when the pages are added..... thumbup.gif

Initial test my bling bling ram = Crucial Ballistix Tracer DDR2 800mhz

mobo : DFI P965 Infinity Dark
proc : Intel Pentium Dual Core E2160

Vdimm : 2.35v
Timing : 5-5-5-15

Wow! That's nice!

What is the best OC at 2.2v? Just asking as I got to know that crucial will only support warranty up to 2.2v. Not planning to go higher than that.....

Just got my crucial ballistix (non-bling-bling) DDR2 800mhz. Can't wait to try it out AFTER I get my new rig!!! sad.gif

Edit: I'm new to DDR2 but can't the crucial run at 1T? Noticed that in the timing tables, it is all 2T.... hmm.gif

Can, but that depends on which chipset on the motherboard you're using.
From what i heard, for LGA775. Only nVidia 680i chipset can go 1T. smile.gif

Dunno about any other platform. laugh.gif

OIC. I'm aiming for the P35 (X38 taking too long to come out!). Maybe this platform can support 1T?

Presently, only the P5K3 Deluxe DDR3 1333/1066/800 and the P5K Deluxe 1066/800 motherboards benefit from 1T technology. The P5K, P5K-E, P5KSE, P5K-V and P5K-VM models will have their BIOS updated in the near future. biggrin.gif

Thx for the info. Will do more research on these mobo.....

Edit : Found a review at x-bitlabs. Looks like the Asus P5K is not really a good mobo for OC. Some random errors too. See here : http://www.xbitlabs.com/articles/mainboard...y/asus-p5k.html

Crucial warrantied all Ballistix & Tracer rams at 2.2Volts.
But how do they know if you put a vdimm of 2.4v and it suddenly kaput? hmm.gif

I don't have the answer for that.
They have their own ways to discover it i think. smile.gif

OIC. Some forumers say that they couldn't possibly know about it.

Anyway, going to get my new rig soon, will keep mine at 2.2v. nod.gif

Just tested out my crucial ballistix PC6400 2x1gb. Would you all say the OC for this type of ram is normal (see below)?

Timings 4-4-4-12, SuperPI stable at:
-2.0v 930Mhz
-2.1v 980Mhz
-2.2v 1020Mhz (but fail orthos, doing orthos at 1000Mhz now, later doing memtest)

Timings 5-5-5-15, SuperPi stable at:
-2.0v 1152Mhz
-2.1v (to be tested)

And yeah, don't worry, I have some ram fans too cool off the rams!!! biggrin.gif

Anyways, Here's my 2x 1gb KVR Hynix FP-Y5. This is the max i can squeeze out from it with relatively good timing @ 2.1v. Not bad.
Nice performance from value rams. thumbup.gif

Makes me wanna go higher for my rams. So far, my rams can pass superPi at 5-5-5-15 @ 2.0v @ 1150Mhz. Don't dare OC it at 2.2v although that is the recommended voltage.

To me, 2.2v + max OC = faster kaput. Below 2.2v + max OC = much slower kaput if ever! whistling.gif Is this logical aaa? hmm.gif

yeap i was suprised the FP-Y5 actually scales that well. It's recommended to go max 2.2v on air and to have a fan blowing over the rams
*
How does it do on tighter timings?

2.2v huh? hmm.gif Ya, crucial ballistix rams also warranty until 2.2v. Hmmm..... maybe I should just set it at 2.2v at max OC.

Yup. 2 fans blowing on it.

I did read some feedback that crucial rams can kaput easily if over 2.3v. However, these are only few reports. That's why I don't dare go too high on the vdimm.

Didn't had much time yest nite to test it. gonna whack it to 2.4v for some trial run this weekend. After some playing around, it wont boot @ 5-5-5-15, probably i guess the lowest it would go is 5-6-6-15. Who knows, will update by then.

Yeap it's not a gd idea >2.2v, unless for a short time of benching. 2.2v is da limit for 24/7.

Ya, I've seen you guys go so high on the vdimm. I'm already sweat.gif at 2.2v..... doh.gif

Some more DDR2 rams prices has gone up, can't afford to have a faulty ram......

Hi, i recently bought an Acer M5600, it comes with a samsung memory 1Gb ddr2 667mhz. When i check the fsb using sisoftware sandra, it displays 1066Mhz tho I haven't done any overclocking at all. Is my PC factory overclocked?

I'll upload the screenshot later coz rite now I'm in the office. Thank you notworthy.gif.

That's the FSB speed I think. Why not use CPUz to check?

That's what some people would do. For me, I usually run memtest when I'm awake and doing something else! I don't want to be waking up to see a million errors!!!! sweat.gif

Managed to tweak my rams further....

Timings : 4-4-4-4
Speed : 950mhz
Vdimm : 2.1v

Pass memtest x3 passes
Pass superPI 32M
Orthosing using blend test......

Yeah, I thought of buying from the US too. However, would be difficult to RMA if any problems.

There was once when one computer vendor was selling the corsair dominator 2x1gb PC6400 (i think, can't remember) for <RM400 due to incredible rebate! Didn't have time to get that as it was only for a short period of time!!!

Of course, to enjoy the rebate, you need somebody living there.... smile.gif

Edit : I know, I know, somebody is going to say corsair dominator is lousy. But what I'm saying is that you can get some parts for damn cheap! nod.gif nod.gif

if im not mistaken larr, superpi wont stress ram or cpu to 100%,

orthos does.. and you can continue stressing for longer period of time..

best to check stability is orthos..

IINM lar.. kalu silap jgn marah..
*
AFAIK, the best way to test for stability is memtest. However, you have to run memtest from bootdisk rather than in windows as the problem with running memtest in windows is that it cannot test all the memory as windows uses a large part of the available ram.... nod.gif

QUOTE(kucingfight @ Aug 22 2007, 02:58 PM)
I disagree, memtest DOS is not consistent. U may pass all the tests there, but you cant boot into windows at times. My best test is to use Prime Blend Test, where alot of rams are tested
*
I disagree too!!! laugh.gif There are a lot of factors that is important for windows to boot. The whole rig has to be stable, I guess.

Since memtest only test the RAMs, it is not testing the whole system and thus may still result in a non-booting windows if other parts of the system are not stable.

I feel that the Blend Test is to test the whole rig's stability...... smile.gif

Edit : This is what I usually do although I'm not too sure whether it is the correct way.

OC ram - test in memtest for stability

OC CPU - test with orthos

OC both CPU & ram - test with blend test for whole system stability.... smile.gif
