What waterblock is that and where did you get it?
It's a Watercool GPU-X (www.watercool.de). Flow drop is only around 5-6% with a DDC pump, so it just fits my needs ;)
Still got to make it fit, they don't have a 100% fitting block from factory right now.
Maybe their 5900XT block fits, I'll check that later on.
What mem is on the non-GS/GLH version? Still the 1.4ns ones (the footprint says they are)? Gainward lists this part with 2.0ns chips. :confused:Quote:

i tried to loose the mem timings but no use of that :confused:
@The Stilt, can you send me BIOS of the GS version on ivcho_n@yahoo.com, because it has not been uploaded in mvktech yet?
GLH version has 0.1V (1.98V vs. 2.08V) higher memory voltage than the non GS GLH version with Infineon 1.4ns memory.Quote:

Hi, i now have my 7800gt no glh.
In difference to the shop info, it is clocked 400/500 but has 1.4ns ram.
I cant go past 1200 also :(
Timings are totally not for 1.4ns, but loosening them didnt help, i suspect its getting not enough voltage, but dont know the measuring points.
But with tightend timings i get 1100 points more in 3D05.
Also, the cards bootup clocks is really wrong, its set to 700Mhz for the ram (!)
Luckly there is no display corruption, and when windows loads the driver sets the right speeds from performance table.
I attached my BIOS with fixed bootup speed, tight timings, and 460/600 default clocks.
So an OCZ 600w PSU doesn't cut it for dual core and 7800gt SLI? WTF? :confused:
Hi , I also have the Non-GLH with the 1.4 ns Infineon RAM . Even at 1120 Mhz it produces random grafic errors. I think it is due to low voltage , even 0,1 V should make a big difference in overclocking , Gainward is undervolting the RAM by purpose. With 2.2 or 2.3 V speed at least in the level of a regular GLH should be possible.
I have tried to flash the card with the bios of the GLH card , but only got loads of graphic errors , so there seems to be no hidden setting for the gaphic RAM voltage in the bios.
We need a hardware voltage mod , anybody suggestions?
And you happen to have a Gainward 7800 GT 512MB and a 256MB? Cause if else by just checking with the BIOS you will not be able to compare the timings! The timings need to be read from the video card to know which ones are active and will then get matched with the TimingSet available in NiBiTor... :rolleyes:Quote:

Ok, my bad :DQuote:

I just checked the differences between GLH and non-GLH bios. The memory timings are exactly the same.
The non-GLH has geo clocks +40, GLH geo clocks +0. Maybe that's why it seems as if the GPU runs better on the GLH models.
Nevertheless mem clocks on the GLH are much better, even if both use 1.4ns memory.
My two non-GLH both ran at around 1150MHz, the GLHs now go up to near 1400MHz without changes to stock cooling been made.
Hi!
I'm an owner of that kind of card,but on the box (wich is green)it writes only Nvidia.
On the back side it writes AGP 8X/4X,and on the other (front side),where officialy writes AGP 8X/4X, is sticked an PCI Express sticker...:slapass:
That's ok for me.
I unmounted the GPU cooling too ,and on the chip it writes:
050926009 0539A2
KOREA
GF7800-GT-A2
P03482.Y00
That videocard performed succesfully all tests, 3DMark(03-05-06) at 530 Mhz GPU and 1530 Mhz Memory O/C, (standard is 450/1300 Mhz).
The videocard runs perfectly,at those settings,with no artefacts,with stock cooling.
Running GPU around 535 Mhz, i saw some small artefacts.
If I try to increase memory around 1540 Mhz,some artefacts appear on Flight Canion test.
What can you tell me about this videocard?
Have someone that kind, with 1,2 nsec memory?
Trying with Riva Tuner, I succesfully unblock the last 4 Pixel Pipeline ant the last 1Vertex Shader,after restart (is possibly???)
Thanks for reading my post!
That's an amazing 7800GT you got there. No doubt you could set a world record with it with some voltmods and good cooling ;)
1.2 ns memory.. damn!
1.2ns sounds nice. My GLH cards both came in the same box as the non-GLH, only with an additional sticker on it. RAM is just the 1.4ns Samsung as in the first post here, clocks around 1.4GHz somewhere.
None...
anyone have this type of card,waiting for impressions
it costs me a lot of flashes but finally I moded the BIOS, so 1.5ghz mem clock on non-GLH version is reached (no volt mods). CL is increased from 8 to 10. anyone who wants to try the BIOS, here it is...
driver test passes even on 1.6ghz, but artefacts appear in 2D :(
some results: 3dmark05
P.S. my 7800GT non-GLH version is with hynix 1.4ns memory. do not flash this bios on GLH version. probably it will not run, because GLH version is with samsung memory
Hi ABATAP
THX a huge lot for your super work! I also have the non-GLH -version too , with 1.4 ns Infineon rams. The bios-flash let me improve to 1450 Mhz stable , 1500 with some tearing , and improved 3D Mark 2005 to 8150 , a gain of about 500 points!
i'm glad to see it works for others :toast:
I recently got my 7800GS+ for agp (24 pipes... g71 gpu) and without any volt mods I get some, for me, decent figures... however, being so close to the 10k limit in 3d5 I'm very tempted to do some volt modding....
Would the 1.4V mod do the thing?
btw... is there a significant diff between the Corsair 3500LL Pro and the OCZ 2gig PC-4000 EB DDR Platinum Edition... which one to choose?
