2x1GB/1x1GB OC Database

**MoToR** · 09-14-2005, 11:59 PM

Well, a bit of info about those PQI sticks on P4C800-E:

Those are PQI PowerMemory 1GB Sticks (aka MD441GUOE - no heatspreaders). I used DRAM voltage of 2.85v, since at lower voltages the RAM didn't always want to startup at all, when overclocked.

In single channel I could get one stick of four to pass MemTest at 225MHz 3-3-3-6, I didn't try to load Windows and check the stability, since Single Channel isn't an option for me.
At 230MHz both 3-3-3-6 and 3-4-4-8 gave me errors at the 98%-99% of Test #5 - about 600 errors.
The 2nd and the 3rd sticks failed the Test #5 the same way the 1st stick did, but at 225Mhz, and passed at 220MHz.

The last stick didn't want to OC around 220MHz at all, the system got stuck on the POST screen, so I didn't test it anymore

.

The strange thing is, three sticks of four fail at the 2-3 last percents of the Test #5 (they don't fail the tests #1-#4, but I didn't go further than #5, probably they fail some following tests too, I really have no much time for this), what is that? What could be the reason of systematic failure at the end of the Test #5?

They don't overheat - that's for sure.

Ok, that's not all, there're 4 more sticks left in the store, I'm going now to exchange the 3 lazy sticks for the new ones, and maybe I'll be lucky to find another stick that will do 225MHz, since I don't need more: 282MHz / 5 * 4 = 225.6MHz.

Another strange fact is, in Dual Channel the sticks don't like the 2:3 divider - 282MHz / 3 * 2 = 188MHz - underclocking actually - but the sticks didn't pass the Test #5 this way...

Why?

Still, the pairs of 1st + 2nd or 1st + 3rd sticks are SuperPI stable at the 250MHz with the 5:4 divider (DDR400) and 3-3-3-6.

By the way, Crucial's Z503 didn't start at 282MHz neither with 5:4 divider, nor with 3:2.
But a pair of Kingston HyperX PC3200 256MB (BH-5 - my 1st RAM) worked perfectly 2-2-2-5 with any divider at any frequency around 200MHz.

What do you say, guys, anything you can advise? Thanks anyway for reading all this.
Lood007 - thanks, man

Got my 2x1gb Crucial Ballistix pc4000 yesterday, so far the fun stops at ap. 265mhz 3.3.3.8-1T 2.74v. (orange slots)

I am a little nervous about feeding them more power, as I have no active cooling for the ram, though they are beneth a TT BigTyphoon. And they feel quite warm already

At what vcore/speed do they require active colling ?

Anyone else running these on the DFI nf3 ultra-d (s939) ? and if so, what are your results? - curious as some seems to suggest the oc-potential for ram on this board is worse than on the nf4 versions?

are you using a high multi? drop it down to like x7 or x8 and see how high they will go.

Sorry about the lack of updates guys. My pc isn't working at the moment, so I'm just grabbing a few minutes on my friends whenever I can until it's up again.

**MoToR** · 09-15-2005, 08:58 AM

By the time I arrived at the store only two sticks left in stock - and both were unstable at 225MHz. "Well", I said to myself, "these are only PowerMemory sticks, I shouldn't have expected anything outstanding from the value memory..."

Next friday I'll receive some PQI's TurboMemory sticks, then, I hope, I'll be more lucky.

**vapb400** · 09-15-2005, 03:51 PM

Hehe i got this stuff for free from an old server at work
OCZ Value PC3200 3-4-4-8 @ 2.6V stock
Currently at DDR450 3-4-4-8 @ 2.6v, havn't begun tweaking yet.

Here it is with just a mhz boost, havnt messed with timings/voltage yet, anybody know what IC's these are? and what vdimm will it die at?

I'm using the UTT/CH-5/BH-5 bios think its worth switching to the general mem bios?

Any tips/pointers for the mem config before i spend the next several hours tweaking it?

**Major** · 09-15-2005, 04:00 PM

Most likely Samsung UCCC, you can see if they will boot at cas 2 @ 200mhz if so they may be Infineon.

I found the 704-2, 1, and 3 all worked fine with both UCCC and Micron so probably not going to see a big difference by changing BIOS. I personally like 704-2 bigtoe mod the best.

**vapb400** · 09-15-2005, 05:47 PM

Hmm, just did some research and came up with this:
The PCB is a B6U808---this is a brainpower right?
On the chips it reads X4E510840A-50----I have researched and the values are supposed to have Elpida chips, anybody know what the rest of this code means?
Also on the chips it says 04 40----That means the 40th week of 04 right?
I knew these were old, but didn't know they were that old.

It didn't boot @CAS2, and I am having problems getting it above 226 (DDR452), It won't even get into memtest at 227 (DDR454) , at 226 (DDR452) it is perfectly fine and can run for hours (havn't tried longer, I'm impatient

)

A quick way to know what die it is, is as follows:

X4I120840B-50
The "I" in "X4I" designates Infineon Die.
E -> Elpida Die
P -> PSC Die
W -> Winbond Die
etc..

So I definitely have Elpida's, anyone ever dealt with these before?
I doubt these will go much further if at all, but I cant complain cuz i got them for free

**aresaid** · 09-15-2005, 06:15 PM

I've never seen RAM lose OC (or die) from 2.8V.
2.8V is definitely safe no matter what chips are on them.

**Doom5** · 09-15-2005, 06:29 PM

My brother has the same OCZ Value memory with the Elpida chips on them. I believe we hit around 225 with cas 2.5-4-4, don't recall the voltage though, could have been CAS 3 also, but I think we were doing 2.5, but it needed a voltage boost. I also remember one of the DFI bios's being really crappy for it, and one working really well for it. Not bad for $197 shipped that he paid.

whats the lowest mulitplier allowed to get into the database?

**giorgioprimo** · 09-16-2005, 12:46 AM

Anybody got the new 2x1g pc4000 gskill kit?

I guess I'll be part of your historical thread enjoy, I'll post some nice data too in a bit on 4 gigs of ballistix. Here's the goods :

it can do 290 stable, but I did 280x10 because that's the oc I have to go for at 1.67volts in bios, my 4400 was limited to 2900mhz max oc.

Oh well, dual fx-57's is not bad at all and $1700 cheaper, hehe.

on a side note, adjusting any ram timings/settings didn't do a damn thing for performance. Trtw set to 2 instead of 3 netted me 100 more points sandra bandwidth, it also made my computer unstable....oh well.

**Jame5** · 09-16-2005, 09:45 AM

Well, I know this is a bit of a letdown after all these amazing overclocks, but I figured I would put my OC into the database to show what an unskilled OC'er can do.

Please let me know if you need any other information. I haven't removed the heatspreaders, so I don't know what chips are being used.

Ehh, I'd be happy to get that high

so don't feel too unskilled. Nice results

290x8 (don't want to go high on the cpu, but i suppose i will try)

Good enough for a share of first place. Just need a verification link.

I like how the extra L2 cache on your FX and the slightly tighter timings shows up as a 57 second advantage over sierra_bound's Venice at the the same CPU speed on your SuperPi 32M run. Did you purchase your Crucial recently?

Yes....i buy from newegg last week.

ok cool, thanx for ur quick answer......i'm excited abou getting my kit

**MoToR** · 09-18-2005, 03:30 AM

Yesterday I got a PQI 3200-2048 DB kit for a test...
Well, I'm disappointed, the memory goes up to FSB225 1:1 MemTest stable, but it won't do even 255MHz 5:4 = effective 204MHz, moreover, I couldn't make it start at 282MHz 3:2 = effective 188MHz, which is underclocking...

What is different when running dividers? Why some memories don't like them?

I hasn't yet decided, should I be disappointed by the RAM or by my mobo, which had troubles running few other memories using FSB dividers too.
I'm a bit tired of all this, but in a week I'll get few other PQI 3200-2048 DB for testing...
