VGA memory chips overclocking statistics

[La1kr0diZ]

I've just found on our site some interesting statistics, one of our friends collected this for about a two years in biggest russian PC forum (forum.ixbt.com)... Unfortunately, there is not enough information about last chips (last update was made when Ti4600 was top-end solution ). So I will be grateful if you'll help to update this list. And it will be even better if you inform about clocks after voltmodding.

You can see real rarities here, so don't be afraid

we should put the memory code there as well since theres more than one samsung 4ns chip out there for example.

DDR SD Samsung TC50 @200mhz (probably bios locked)
DDR SD Samsung TC40 @280mhz(artifact free) @310(max oc)
SDR EtronTech 3.3ns@300mhz(artifact free)
DDR SGRAM Infinion ?ns@190mhz(artifact free)

[La1kr0diZ]

exactly what is needed!

Maybe it will be useful if we also put some card info. I.e. 2.0ns mem on R9800Pro 256M and FX5900 overclocks differently...

Ok, here is bunch of cards from last three years...

DDR Samsung 2.0ns @ 530 (artifact free)/548 (max oc) - FX5800
DDR Samsung 2.8ns @ 360 (artifact free)/382 (max oc)/390 (V=3.15V, no h/sinks) - R9800
DDR Samsung 2.8ns @ 388 (max oc) - R9800
DDR Samsung 2.8ns @ 376 (max oc) - R9800
DDR Samsung 2.8ns @ 360 (max oc) - R9800
DDR SD Samsung 2.8ns @ 378 (artifact free)/384 (max oc) - Ti4600
DDR Samsung BGA 3.3ns @ 360 (artifact free)/370 (max oc) - Ti4200-8x
DDR Samsung BGA 3.3ns @ 351 (artifact free)/360 (max oc) - Ti4200-8x

DDR SGRAM Samsung 4 ns @ 225 (artifact free)/250 (max oc) - GF2 Ti VX
SDR SDRAM EtronTech 4ns @ 265 (max oc) - GF2MX400

bump

[JCviggen]

DDR SGRAM Hynix 4ns @ 280-290

you know I got a 9600pro here with that mem, default is 200 MHz, at 209 MHz it artifacts and it totally crashes at 215

[saaya]

9600pro with 200mhz memory? ouch!

4ns=250mhz ...wtf? baaaaad memory they probably recycled some old cards and used that ram on the 9600pro cards

[Stang_Man]

anyone know what RAM this is:

from my 9700Pro:

Samsung 310
K4D26323RA - GC2A

[saaya]

3ns i think

[ellsworth]

what are some statistics for the infineon 3.3ns on the 9500np's and the 9700np's? curious. La1kr0diZ i know you have a really nice 9500np, how far did you get your memory before a vmod, it has the infineon chips im assuming becasue the hynix chips suck.

[W1zzard]

3.3ns infineon without voltmod go to about 305-311 mhz

[ellsworth]

well my my, look who it is . i like your drivers W1zzard. thanks for the info.

[charlie]

Stang Man,
It's Sammy 2.8nS
C

[ellsworth]

those numbers are with volt mods i assume? 358mhz is very nice volt mod or not.

[BigDov]

hmmmm......... 3.3ns EntronTech BGA on my Ti4200 is currently at 675, no voltmods, no artifacts. Looking to go a bit higher too!!!
