Count me into the club. Got a genuine reference MSI board off of a forum and so far it is clocking nicely. I don't think I'll be able to reach the golden 1000/1200 as the memory artifacts pretty badly above 1150, and 1000 core won't go in Kombustor even with 1.275v. So 950/1150 1.225v for 24/7 use seems pretty sweet.

bit late but yeah seems to be the case above 950mhz is what separates HD5870 cards, not that a bit more voltage won't fix

hey all,
i have a HD5850 - asus branded - but reference design.

The fan on my card seems (to me) to act strangely - it will spin at <300rpm until temps reach 85c or so - then it will spin up to a very high speed till the temps come back to "normal"

after this the fan will idle at ~1500rpm until there is a high load, where the fan will go slow (again <300rpm) until hot and then it seems fine after this.

Ive tried custom fan profiles, both software and bios ones and doesn't change anything.

Additionally - whilst the fan is at ~300rpm, i can set the fan speed to 100% and nothing will change.


Im running the 10.x drivers atm (early release 10.5s) but have run the 10/2s also with the same issue.

this isnt affecting the performance of the card as far as i know - but its annoying me somewhat and when the fan is at ~300rpm, its annoying as you can here the pwm of the fan kicking in and out.

the card was bought second hand from OCAU, but the previous owner had 2 cards, i pm'd him and he said that his other card did the same thing also.

just wondering if this is a common thing/if there is any fix of any kind?
haven't paid much attention to HD5850s, but first thing i'd do is find out if there's any bios updates for your card - could be a fix out there. Tried using MSI Afterburner, Rivatuner to set fan speed ?

First time pushing beyond 1000mhz on single Sapphire HD5870 stock hsf flashed to Asus bios. Broke 24k single HD5870 @1050/1281 with i7 980X @4Ghz.

Hi all, not been here for a long time.

I want add a second 5870, and i m a bit lost with all the new model, specially with the Blue PCB ones, I have see it's impossible to adjust voltage on some with Afterburner, don't know if it was faulty models, but it will be really bad to fall on a card i can't OC....

Actually on the my shop, they have only some few model with 1go available, need check if they can order specific only for me. But any input about thoses one ?

- Asus 5870 Revision 2 ( witht the new cooler, not the matrix ) http://www.asus.de/product.aspx?P_ID=iAXaiw2KfP5w0xU0
Look like this card can easely reach 1ghz+ with the stock cooler, but can i use MSI afterburner with the voltage tweak of Asus ? for OC both cards in crossfire )

- Sapphire 5870 Vapor X and Toxic
- Sapphire standard model

- Gigabyte 5870UD http://www.gigabyte.com.tw/Products/...ProductID=3355
- Gygabite standard reference model

- HIS 5870 V Icooler turbo (875mhz and Turbo X 900mhz models ) http://www.guru3d.com/article/his-58...-turbo-review/
- HIS 5870 standard reference model.

- The XFX 5870 XXX

Sadly nothing great as the Matrix or the SOC, Lightning.... Need check if i can find a shop in Deutshland or France where they can sell the MSI...( Euro is low right now, so i win a lot of money on the exchange rate )

Hey Lane been a while

all the models you listed don't use the reference Volterra controller with software adjustable voltages But at least the Gigabyte one has it's own software to adjust voltages up but i think 1.3v or 1.35v is max allowed. Asus HD5870 rev2, lakeside in this thread reported it didn't clock anywhere near as well as the first rev reference Asus HD5870.

I'd just get a HD5870 reference model i.e. HIS one to match your existing one, much easier to adjust voltages
