X1800XT Overclocks

[melchy]

A lot of us took advantage of the pricing on the X1800XT over the last week or so. I thought it would be quite interesting to see what sort of overclocking results people are getting with the cards. Personally i just used the autodetect settings in the CCC overdrive panel. If i recall its something like 693/798 which to be honest i've no idea if its decent or not, not really knowing what the cards are meant to do.

i flashed mine to the pe bios which run's 100mhz more on the core and 100mhz more on the memory. checked my board to make sure it had 6 power resisters and away i flashed. so now i have a sapphire x1800 xt pe, ha ha. had no side effects whatsoever. i now score 10,056 in 3d05 on standard settings.

i can get my core to 700mhz but mem is being a prob and i cant get it over 770 this gets me 9.8k in 3dmark05

i 2 have the 6 power thingys but my max temps at 80c and i dont want to increse that temp anymore

im using a lil tool called "overclocker"

the ati ccc will only let me clock to 688mhz on the core not done mem

and ati tool wont let me get core over 640 with out artifacts :S (very strange as overclocker does)

im testing by running 3dmark05 once and then Counterstrike:source @ max settings

 

[siclilmonkey]

any1 got any idears?

 

[Goksly]

Does the PE bios alter the voltage at all?
Im interesed in lowering the voltage as much as I can without lowering the clocks.

 

[siclilmonkey]

im not sure i got told it did my max temps r 80c and dont want to incress them any more

 

[hannibal2381]

i didnt notice any rise in temps. and did you change the settings to 3d ??? (overclocker)

 

[siclilmonkey]

yup change to 3d then got 2 702mhz core but i then tryed ati tool and that wouldnt let me go past 640 on hte core

 

[hannibal2381]

ati tool wont let you change 3d speeds its just locked on 2d speeds. thats why there are artifacts and stuff.

 

[jrodga2k5]

yeah pe bios gives you a 3d speed of 700 gpu and 800 mem! ati tool does infact tel you there are artifacts very early on no matter what, there is no great tool to be honest for doing this yet

 

[siclilmonkey]

iv been using the overclocker program

its simple layout is great but can be tricky to use caus u have to incress core by 7mhz a time and mem at 9mhz a time

havent used the voltage changers yet as i want the max stable oc at stock volts

atm its about 702 on core and somthing like 760 on mem

im using riva tunner for monetaring of temps clocks and volts

I flashed my powercolor x1800xt 512 with the sapphire pe bios, and i get 9541 in 3dmark 05 . I could propably get it a bit higher, but I'm pleased...

whats your spec ? i got 10,056 but that was with the opty 146 @ 2.9

I have an x2 [email protected]. If I could increase the Vcore for my cpu, I could propably push it much longer. Unfortunately, my asrock 939dual sata2 won't allow me

 

[Metalface Mark]

using xtpe bios 8400 in 3dmark 05 - thats with a 3ghz p4 @ 3.5 though.

AMD Opteron 146 @3ghz
DFI Lanparty NF4 SLI-DR
Crucial Ballistix 2GB DDR PC4000 (2x1GB) @ 273fsb (DDR 526) @ 3/3/3/8
Enemax Liberty 620w
HIS Excalibur ATI Radeon X1800 XT 512MB GDDR3 AVIVO TV-Out/Dual DVI
2x 160GB Seagate Barracuda 7200.9 NCQ SATA-II - *Raid 0*

thats my spec and im getting aroung 9.8k on 3dmark05

core = 702mhz
mem= 765

stock voltages

temps 80c give or take a few c

that is max oc with this card using the overclocker program

if i up the mem i get artifacts if i up the core i have to restart.

Try flashing with the pe bios, you should easily come over 10000 points then

 

[siclilmonkey]

update

core = 708mhz
mem= 784mhz

stock voltages

temps 80c give or take a few c

upped the fan speed to 55% to get this incress

now getting 10k

 

[BS Dave]

mine does 690/800 using ccc, which to be honest i'm pretty happy about, not sure i wanna try flashing the bios for an extra 10mhz

 

[hedgey]

does about 680/1700 but I dont oc it, doesnt make any diff in games.
