*** Official Radeon HD5800 Series Overclocking Thread ***

Here's my personal best so far with my 5870. I haven't hit a wall yet on core or memory so I will keep pushing. I am currently running a stock card with stock bios and stock cooling.

XFX 5870 1GB XXX Edition - Stock Cooling
Core i7 920 Batch #3913A330 - Water Cooled
P6T Deluxe V2 ~ Bios 0006
Kingston HyperX 2000Mhz CL8 3x2GB Elpida Hyper
Corsair TX850 PSU

I am only using MSI Afterburner for both voltage adjustment and overclocking.

Will keeping pushing. Looking to get a nice full cover block for this card once I max out my clocks on air. A nice cpu with a higher multi would be nice as well. This Board has a bclk wall around 218.

Catalyst 10.1 is out - downloading, thanks! :D

I can overlock my card 10Mhz+ with these drivers!
Why? I can't explain!

strangely for me it wont let me do some 1115core vantage run with new catalyst driver. But i might go try out furmakr to see my best 24/7 max clock

I haven't pushed it really hard yet, but, here are my preliminary results.

I just got the card yesterday. It's an XFX, vanilla, 5870, on air until my ek blocks come for it. I say blocks because my second card comes tomorrow.

Here's at 950-1250. I flashed to the Asus bios and I am running cat 10.1 drivers.

Nickless you rock .. awesome score you got and thanks for the tips in a week or so , il post my attemps using asus bios :D

Got my second 5870 and put it under water tonight... Preliminary results:

This is at 1100 1310 @ 1.337v

Great 5870 clocks and CF score!
Would you please run all of the 3dmarks with a single card at 1100mhz core and post them on HWBot? That'd be awesome! :yepp:

L33T voltage! Smartdoctor might give you a little more vcore ;) AND, if you know how to edit your bios, the newest RBE beta supports writing the second vt1165MF's registers to increase memory voltage as well (5870,5970)

Thanks guys.

I did notice the elite-ness of my voltage. LOL.

I'll do single card on hwbot. Just give me a couple days. I just can't bear to tear it all apart right after getting the loop together. I got both (06+vantage) my dual card scores on there.

validation
heaven scores
3.8GHz 3 cores, 5850 725/1000

3.8GHz 3 cores, 5850 1000/1200
http://www.overclock.net/attachment....1&d=1264908870

Strange stuff. I can't seem to adjust vcore anymore now that I'm on 10.1. The option is grayed out in Afterburner.

Anyhow, if I don't touch the voltage I'm apparently stable to at least 800/1150 on this 5850. My previous results of crashing instantly at 850 using even 1.25V seem odd now. Any ideas what might be going wacky? I'm also miffed why I can't get to at least 1250 memory at default voltage when that's the stock rating for these memory chips. Are they fed less voltage than whatever they're rated at by default?

This thread has been very helpful. I'm a noob at OC on vidcards. I've never flashed a bios, or done anything aside from running the auto tune in the ATI overdirve software. I have a saphire 5850 and I've downloaded MSI afterburner. Could you guys recommend a solid oc setting for my card? Currently it's set to 725 core and 1000 mem. I guess the fastest the current bios will let me set it is 775 core 1125 mem? I plan to utilize the stock cooler.

Flashing the bios scares the crap out of me. :eek: I've never done it before. I need to look for a good walk through on it. Any information would be helpful cuz i'm clueless...:shrug: Thanks.

too lazy for screenshots right now but..
http://service.futuremark.com/compare?3dmv=1853691

5850 at 1000/1250 and 1312 core voltage
cpu reports as 3.6GHz but its really at 3.2... for some reason it wont accept anything less than max multiplier in vantage... oh well.


*edit*
so apparently Modern Warfare 2 was more of a challenge than Vantage was... had zero issues in Vantage but MW2 locked up as if there wasnt enough volts as it did in vantage before i jacked up the volts... already pushing 1.3+ into it.

That link really helped. I'll have to set up a USB stick. Do you have a bios file you could reccomen for my 5850?

http://www.xtremesystems.org/forums/...5&d=1257556756 this should be an unlocked one (see OP).

any tool to flash bios under Win7 64bit?

Flashing under Windows is not recommended.

Hey guys, I need some help.

I recently bought a 1080p monitor, and as nice as it is, my 4850 really struggles with every game I put at it, except for CSS or TF2. Now my questions..

1) Will a 5850/5870 bottleneck my E8400 4250Mhz?
2) Would it be worth upgrading to an i7 920 ontop of that, and ocing that to 4.0 GHZ...will that give me a decent FPS boost when paired with a 5850/5870 when compared my current overclocked CPU? What I mean is

E8400 4.25 ghz + 5850/5870
Versus
i7 920 4.0 ghz + 5850/5870 = How much more of a boost?

3) I hear you can OC a 5850 to 5870 speeds, so would it be better just to buy a 5850 and OC it to kind of get near 5870 speeds?
4) How about 5870 overclocking? Would it be worth more to buy that for 100 bucks more and oc that instead?

Thanks.

No point to go i7 imo, you can try and push your CPU a bit higher, though, and that'll be plenty.

@dark-energy: is that 4850 512mb version? what are these "other" games? and are you trying to run at ultra high settings and ultra AA settings? imo no point investing in i7. and 5850 oc to 5870 speeds pretty easily... though i think it's the extra vram gonna make you feel a playable difference.

@frogeye: just use atiflash and save your original bios, mod it with RBE v1.24, save new one, flash card(s).

my question: i've seen some people with ridiculous high mem clocks like >1300. is that reasonable to expect? on my cards i'm thinking it's the mem clocks that it's not liking. i've bumped core volts up and i can get core up to 950 at 1.2v (could probably go lower volts) but the mem doesn't seem to like going above 1225ish before crapping out.

edit: i have 5850.

10.x driver....
