yeah my bad, will test again with 3dmark11..sorry bout that

Hi guys, i hope im not too late to join in.
Sapphire 7870 OC (1200/1450,stock voltage)
http://www.3dmark.com/3dm11/6508420

welcome bro , wow nice clocks at stock voltage + the score
let's try another benchmark especially those build in games benchmark

Can suggest what game should i use? Currently only have Hitman,Tomb Raider and Far Cry 3.
Edit: My vrm temp is hovering around 75-79 but sometimes it jumps to 95 to 255. Is it bug or wat? Using the latest GPU-Z.

the 255 is a error cause ure i/o is clashing with another software thats reading from the same chill/ic.

close the other

Hey guys, i wanna ask should i still oc my 7870 xt if the vrm is getting 97'C, core 81'C max with core at 1100mhz and ram at 1500mhz. At default, the temp is like core 75'C and vrm 80'C. The vrm can boil egg and feel that it is not good for the long run although it is rate 125'C. What do u think?

Here are some screenshots on VRM temps with 13.1 vs 13.4 vs 13.5 b2

13.1 stock 41C only


13.1 OCed 1320/1750 top 62C


13.4 stock already 59C, OCed 1320/1750 instant crash


13.4 OCed 1250/1600 top 87C before even running any benchmark LOL


13.5 b2 stock already 54C, OCed 1320/1750 instant crash

Owikh check hwinfo on the vid. Maybe driver is forcing the vid.

Also can u use trixx 4.4b mod

my 7950@1100/1500

hmm dunno why after launching hwinfo64 and TRIXX and one reboot the VRM is working fine now in which 13.4 and 13.5 b2 yields the same VRM temp as 13.1.
Just required slightly more VDDC than 13.1.

so i suspect ab error.

sorry cant test cfx 7970 with 13.5b and 3dm11 coz one of my 7970 dead, system unable to detect it.. I think due to WC leakage that happen recently. too bad as now only have one 7970

Nice OC and score bro, is that clock 1100/1500 entirely stable for 24/7 for gaming?

arghh that's s*cks. Hopefully your card will return as ref 7970. Good luck bro.

ya I hope so,thanks Kevin. chance is very2 slim ..maybe I'll use it in prodigy if non-ref or sell it off later saving for next-gen AMD? really cant wait haha

i ran furmark for 4 hours and didnt notice any artifact on screen, probably can push more if using AB..

Increase some voltage and up your clocks...Run it with heavy games like crysis 3 to test for artifacts or stability running it for like 2 hours is good...i personally dont like furmark..

overclocked my 7870xt to 1100 mhz, Folding@home above 60000 PPD

this score is only for the card

add my 3770k total will be 95000 PPD

full load 1100 mhz @ 65C

7950@1200/1500. CPU only @4.3ghz my cpu cooler is limiting me from pushing it further
