thanks Cryptik, upon reading the 2.0vdimm, i rebooted my PC and set it to 2.0v (reads 1.98 in Everest), still need to test if stable during apps/games.

S/N from the box of my kit is PH220071128002

@OC/43 & Cryptik,

do you happen to know the serial numbers on those kits?? so i can have an idea on what the chips on my rams are w/o prying the HS off.

I also have the same mems that I got as replacements for my TG Dark 2x1gb pc6400 because distro went out of stock with the darks and only TG Elite 2x2gb ddr2-800 and the ddr2-1066 were available when I RMAd it.

i'm currently running it stock @ 2.3vdimm in bios.

btw, mine is week 35/07

My s/n is 200805280781

I find it funny to see so much Cell-Shock kits dying because i know Cell uses 8-layer pcb and can withstand voltages very good and yet ppl lose them at 2.0V or so, now that's just lame, how did D9 get so moronic, they weren't like this before...

My CellShock are OK, it was my board that became unstable, and I misdiagnosed it as my ram. After increasing the vNB 2 notches, its rock solid.

They are now at 1113 MHz, 5-5-4-12 @ 2.00v

I was thinking along the same lines, I was going to put up a thread asking about whether people thought naked kits of D9 lasted longer than the kits with spreaders. They get really hot, as all the IC's are touching them and transferring heat, but also due to that fact they are keeping the IC's hot too. I'm not sure what temp each individual IC gets up to under load, but I doubt it would be as hot as the heatspreaders are.

Yeah I think I will remove the heatspreaders. Only skeptical to do so as the kit is so new, but even if I do need to RMA the sticks after a bit, its not like thermal tape is difficult to find

Just glue the HS back
I done this and manage to RMA my Crucial Tracer 800mhz 16FD3

AFAIK CellShock don't use thermal tape, its actually thermal paste put onto each IC and then the spreaders are bolted on (hence why the spreaders get so hot - they have good thermal transfer), so you could just re-paste them, and put them back on. They have a weird star shaped bolt head though (like on mobile phone bolts) and you need a special screwdriver. If worst came to worst, glue is an option lol.

[mad_skills]

Also, Cell-Shock does a nice job with the heatspreaders and they cool properly, at least one manufacturer with which u get what you pay, no need to change ram sinks etc.

D9JKH is a 1Gbit (128Mx8) DDR2 chip binned at DDR2-1066 by Micron.
It is being used primarily on singlesided 1GB modules or doublesided 2GB modules.

My D9JKH... Pretty bad on my P35 board, but I'm sure they're better on the newer AMD chipsets that support DDR2-1066 @ 1.8V.

Voltage is only 2.0V. They don't scale much higher @ cas 5 with more voltage...

[Ket]

If the sticks were cheap, then I guess those results are "ok". But still... bleh. Nobody likes crap clockers.

[CryptiK]

Not bad for JKH, so from those results and your sig, it seems the gain an extra 125 MHz by going to CL 6? CL 5 at DDR1000 should be faster I would have thought.

mBIOS803. Thx Ket.
Cellshock 1000@4-4-4-12 D9GKX 2.2vDIMM
4GB@1243
I need better cooling to get further...
But this is my 24/7 so far. Folding stable and all.
I had em booting 1400@2.3 but that would take some serious tweaking to get into windows

[knopflerbruce]

I have an old G.Skill HZ kit that I tried a little this weekend. The result was 560MHz 1m @ 2.3v 4-4-4-5. 570 managed to boot, but not 1m stable (lol). Is this decent for D9's, or should I look for better sticks?

[Retro]

My Team set (TXDD2048M1000HC5DC) 2X1GB PC2-8000 D9GMH does not perform well with my Asus P5Q-Deluxe.

They run fine up to 450 fsb on the 9x multi, anything beyond bsod's. Same with trying any half-multi, none work. With my previous Abit IP-35 Pro, the Teams would do anything, had them up to 500 fsb, could use the half-multis, etc. No errors with Memtest. I have tried many combinatios of settings and voltages to no avail.

Leeghoofd suggested that there may be a memory incompatibility, sure enough, I swapped in the only DDR2 ram I had on hand, a cheap 1GB stick of PC2-4300 Crucial Rendition. Now I can run it up to 8, 8.5, 9 and had it up to 471 fsb, no more bsod's. Just as it should be.

I'm looking at a few of the brands it should be ok with, G. Skill PC2-8500, OCZ Reapers, Mushkin Redlines, HP and XP etc. so I am going to try a new non-D9GMH set.
Unless I'm missing something here

Look for better sticks, thats a very decent result, but you should be able to find handpicked samples that blow that right out of the water.

It only takes 2.26v for my teams to handle 610 4-4-4-4 1M stable. So those are nice if you dont care and want to suicide 3V plus for max speeds, but for serious benching handpicked FTW.

[Ket]

Done some speed data editing of my Cellshocks, will be testing them out soon

[Ket]

Finished with a little messing. Not too bad. Think I will go round my m8s tomorrow though to flash a more customised speed files to this Cellshock kit and 4 of my other kits. That way timings are more or less what I want. More specifically, my Cellshock new speed data file has timings of 5-5-5-18-42-42-4-8-4-4. Tras will manually be set to 15, but in the speed data file 18 is as low as it gets for proper tras settings at other frequencies.

[CryptiK]

Nice what voltage for 570 5-4-4-12? And did you mean to write 42 twice in those timings?

My 24/7 for my CellShocks is 556.5 MHz 5-5-5-12, tRFC 30 @ 1.96v

[Dee]

Currently still tweaking, but being quite lazy about it. Here's my current 24/7 settings. Nothing extreme, but I'm happy with it so far. As there's no active cooling, and because I would like to keep this RAM alive, I'm reluctant to push tons of voltage through them just for some slightly tighter timings (which will make no major difference in the real world anyway).

[CryptiK]

Nice Dee, I like these CellShock kits very much too Is that 1.9v BIOS set or real voltage?

[Dee]

It's 1.9v in BIOS, Cryptik. I can't measure it any other way, unfortunately.

[CryptiK]

It's probably closer to 1.96 - 1.98v real, if you have a DMM perhaps verify what it is. That's what I had to do with my P5Q-Deluxe, and found it over volted by 0.06v from whatever I set in the bios. It's still a nice low voltage though.

[Dee]

Yes, you're probably right. I don't have a DMM. I should get one.

[Ket]

Ok, I went round my mates today and borrowed is board so I could flash new speed data to my Cellshocks Timings currently are 4-4-4-12-42-42-4-8-4-4 @ 2.2v 1040MHz. I'm going to change voltage to 2.1v as it should be more than enough. Unfortunately nomatter what I do my system does not like higher memory frequencies than around 1040MHz. This limit has been observed with three different memory kits now so it's deffinately not crap memory. The only thing I have concluded it could be is my CPU not liking frequencies much past 1000MHz, so its deffinately time for a new CPU... time to sell some stuff

[Dee]

Which CPU will you get?

[CryptiK]

I just figured out how to clock ram high on my M2F. The setting that made no difference at all on my P5Q-Deluxe, made all the difference on my M2F.
