G.SKILL F2-9600CL5D-4GBPI Sample testing

I was a beta BIOS X48ADA02 very upset, very much cut, compared with X48AD829, dispersing poor, had to go back.
If interested, please see my review G.SKILL F2-9600CL5D-4GBPI

Great stuff; thanx for removing the spreaders.

I'm a bit confused though...it's said this stuff is PSC, but it looks like what i've heard is ProMOS?

Here's the same type of IC (look at the pic) is said to be ProMOS.
Chaintech Apogee GT 2x2 GB DDR2-1066

Here's some Transcend AxeRAM 2x1 GB DDR2-1200

Same type of IC design.

So something's not right here.

Either this different looking IC is actually a higher end type of PSC that looks like what some say is ProMOS, or it's actually ProMOS?

Direct pics for comparing.

G.Skill 2x2 GB DDR2-1000 = PSC (thanx to Miravo)


Mushkin 2x2 GB DDR2-800 = PSC (thanx to t-break)


Transcend 2x2 GB DDR2-1066 = PSC (thanx to s e t h)


I have a ton of other pics of PSC on different kits; we all know what PSC looks like.

Chaintech Apogee GT 2x2 GB DDR2-1066 = ProMOS? (thanx to Miravo)


Transcend 2x1 GB DDR2-1200 = ? (thanx to nicepun)


G.Skill 2x2 GB DDR2-1200 = PSC? (thanx to high-gertz)


This "PSC" is a different IC layout than i am used to seeing in PSC...

Anyone know what the real deal is?

Because if this is PSC, then that Chaintech Miravo said was ProMOS is PSC, as is the Transcend @ DDR2-1200, which would indicate this is a significantly higher rated PSC IC than the normal ones.

I had two PC9600 G.skill PI (only 2 as I can't buy more in Europe at that moment, I am waiting for 3 sets about one month...) The first retail supply was PowerChip (the same as in PC8800 PI) and now is ProMOS in PC8800 and PC9600. This ProMOS is also awesome and can do about 1200 - 1300 what of I have seen till now. It's used in Mushkin XP2 PC8800 2x2 Kit ( my set does 1230 MHz stable if I remember correctly) and G.skill PI 8800 does about 1150 - 1190 (I tested 7 kits two weeks ago).

$300 for your used memory you been overclocking and pumping high voltage into, no thanks will wait for new stuff for that price, thanks anyways.

i never went past 2.09v n they running only 1230mhz 2.06v@ 515fsb 24/7 24c
and they will be in the for sale section soon and cheap
i gettin a nahaleem itch
too bad you dont have 100+ posts

[neo mike]

Why do i need 100 post ? im interested in them, but not for $300, im tired of waiting for these things looking for other 4gb kits, but right price, i paypal you right now.

Sorry if this was already posted, Indonesian review with spreaders off, says it's Powerchips:http://www.ur-hardware.com/Memory/G.Skill-4GB-PI.html

Those have gotta be the worst pictures of ICs ever.

Anyway, in spite of the horrible focus & distance of the pictures, one can still see the layout of the markings on the IC, & they aren't PSC markings, they are ProMOS ones.

See my previous post: http://www.xtremesystems.org/forums/...&postcount=145

Top three pictures in that post are PSC.

Notice how the dot is perfectly centered to match the bottom line of text, & notice the font style/size.

Bottom three are ProMOS.

Notice how the dot is slightly lower than the text, & the font is smaller & different than the PSC's.

Then compare to the Indonesian Hardware reviews pics...
It'd be nice to have a decent pic, but i can already tell it's ProMOS, even from the blurry pics.

Thanx very much for the info.

I kinda was wondering why this stuff was doing so much better than the normal PSC was.

So we have a new 2 GB DIMM champion, ProMOS

You wouldn't happen to have any pics of your findings with those other kits now would you?

LuckySevn - Those GEIL Evo One modules are very decent and I almost got them instead of these GSkill 4GBI's (plus their much cheaper)! $300 is indeed very expensive for a 4GB kit of DDR2 but after having them for a week or so I'm very happy I bought them and will definately keep them for a while (at least until I make the switch to i7).

In regards to the IC's used on these modules I'm not 100% sure because the heatspreader is difficult to remove (much harder than my last kit of GSKill RAM that had the clips instead of the adhesive thermal pad used now). However I was able to carefully pull-up one side of one of the modules and they look just like this I think (but its hard to say without fully removing the heatspreader)

If I am able to safely remove the heatspreader I will take a few high-resolution photos and post them ASAP! I can also say that this kit scales pretty well with increased voltage (just like Denny's results show at the beginning of this thead). I didn't go past 2.10v in BIOS (which overvolts to about 2.18v-2.21v) but I feel confident that it would have continued scalling for a bit.

You had also asked about Vista and if these modules run on it, well my kit is running very strong on both WinXP SP2 and Vista 64-bit SP1. I haven't had a single issues with either OS and I've done lots of benchmaking and gaming on both OS's. I'm surprised your not having any luck with Vista using those Evo One modules but its clear from your picture above that the 4GBPI's are using different IC's (at least from what I saw and what I think they are). I'm even more interested in pulling this darn heatspreader off but like everyone else I also don't want to kill my very expensive RAM! Let me know if you want any specific Vista/XP results or tests and I'll do the best I can.

No need to pull your spreaders -n7 linked me already, they're ProMOS. Plus I wouldn't want you to risk $300 lol! There was another guy in Taiwan with these EVO's and he got 'em running DDR2-1200 @ 2.0v in XP 64 just fine, but he's on DFI. He said he couldn't boot into Vista at that speed. So I really don't know...it's probably just the chips, not binned high enough or they're just not 100% stable for Vista. After seeing the results on those PI's, I'm getting crazily anxious about grabbing a set.....that's how I went broke....but just can't resist it...

If you could show me some Everest and game benchies with those in Vista I'd really appreciate it! Thanks man~
