Anyways here's my KVR 2x 1gb DDR2 667 Hynix FP-Y5 assembled in China. Not bad, 2V @ DDR2 1000. Loose timing tho.

quite good for FP-Y5.. i thought they max out 900..
not try 2.1 or 2.2v?

Yeap i was suprised myself it could go so high, yet alone ORTHOS stable. I'll be finetuning the settings and see, with better timings.

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.

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.

currently, from the previous findings of D9 on Value rams, are only D9NHL. Even then is hard to find them now. Mostly on Elpidas now

Why in the world do you want Hynix FP-S5?

Those are Great Chips. equalling or better than those OCable D9s. VR zone has a review on it.

Anyways, tested 2 sticks of KVR ddr2 667 , Kingston chips. Hit ddr2 1040 5-6-6-15 @ 2.2v. Pretty decent.

Pretty decent? Thought value 667 to reach ddr2 1000 already wonderfull. hmm.gif

it's decent so to speak, in a good way. Btw's I'm planning to do some database test on any value rams, i hope you guys , the good hearted ones can 'loan' me some sticks to test it on.

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
*
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
*
Well yes off course it depends on other factors. Let's assume we are talking bout rams overclocking since we are on this topic anyways, and leave out other factors. It has been said over a few times that Memtest isn't a proper test tool for ram testing purposes. Blend testing is sufficient as it taxes the rams quite a lot

1.lousier D9 outperfom hynix ?
2.how abt D9DQT , saw on the 1st page , good oc ability ?
3.beside D9GMH D9GKX , wat is the best recommend ram chip ?
*
thing is, there's no 'cheap' D9 on the market now , even more on Value rams. (unless you can really dig out those really really old stocks)
If ur lookin for chips other than D9s, the elpidas and promos will do tight timing at low speeds, eg: 4-4-4-10 @ ddr2- 900 the max. it wont scale higher even with added volt or loose timings.

The Hynix FP-Y5 is indeed proven to go above DDR2-1000, CL5-5-5-15 off course with relatively little additional voltage (1.9v-2.0v)

If i were you, i would go for patriot values with hynixs

I m using Kingston Value RAM 2GB 667Mhz  1GB is Hynix, and another one 1GB is Micron chipset

So, I Overclock it to 800Mhz without adding Vcore, should not be a prroblem right ? I don't not tune the timing etc....

As always..juz try, tune and do loads of tests..that's da only way

FPY5 can scale higher than elpidas. Elpida are good at around ddr2 900 max only

I'm still rather confused with the "handpick" term smile.gif You mean these are specially selected RAMs out from the factory and they perform better than the rest?

Probably it's something like speed binning. the choose the 'best' of the bests for annies.
