CryptiK It's been real, gentlemen.

After 7 years of 2-way then 3-way SLI with my own custom powerlimit raised Hydrocopper BIOS running 1045/6000 @ 1.15v with EK Blocks, I have upgraded to 2-way Titan Xp's

The OG's would sit on around 340,000 PPD each with FAH, the Xp's produce ~1.8 million PPD each. In 3D the gap isn't as huge, but it's pretty huge.

I never realised some of you were pushing the VRM's so hard and running 1.3-1.4v long term, I'm staggered they didn't go up in flames. NVIDIA aren't known for stout VRM design and indeed reviews of the cards suggested it was by far the weakest link. Incredible!

skupples i feel like we were chasing something like 12-1300mhz @ 1.4v, i'd have to scan back to see though. 1.21v was possible without buck controller hack.

glad you got it working.

DmitryFX Thanks for your info, I have finally risen the Power values some more and voila, I have stable 1045-1100MHz (depends on my OC settings in MSI AB) and 78C max/1.16V max
Superposition - 6400Pts.
I'm happy for now)

eduncan911 Ah, you're right. It's in the first post of this thread! Lol

skupples ^^ essentially, but LLC mod broke.

we were directly controlling the buck controller via cmd, after some sorta msi ab mod.

its all pretty well documented in the OP if I remember correctly. just ignore the LLC.

flash over high TDP bios >> crack buck controller

pretty sure some of us were running 1.4 for years on end.

we caused such a ruckus that Nvidia sent minions over to tell us this was placebo.

sorry, NV, clearly you can see on our DMM and 3Dmark scores its not placebo.

eduncan911 We use a custom bios increases the power limit and removes that dynamic boost (can't remember what it's called).

IIRC, the bios was released by Skyn3t.

There's also a Windows tool that stabilizes the voltages, can't remember what that is called at the moment... maybe LLC Mod.

To let ya know, I was pulling nearly 430 watts from the wall per GPU (I had two), which the power meter showed something like 1005 watts, up from the 150 W idle or so when I was mining on them at 94C for months. They are bullet proof.

Edit: Found an old Post where I outlined the differences of the Skyn3t bios, with the version number to search for.


Search around here for that version of the bios, maybe even this thread.

DmitryFX Hi! Anybody alive here?)

I still own a Titan, going to change it to something newer in the near future, but now I'm trying to get some more power from it.
The problem is a constant PerfCap - PWR, even at pretty low voltages and frequencies.

I saw the people here were able to run their Titans at 1100+MHz and 1.2+V
How is this possible if the card utilizes ~230W and then throttles beacause of the PWR Limit?

Some facts:
Zotac GTX Titan AMP!
PSU: 1200W Thermaltake TR2 RX
1006Mhz - 228W - 1.1250V - PerfCap PWR
1019Mhz - 222W - 1.1370V - PerfCap PWR
966Mhz - 211W - 1.0870V - PerfCap PWR
ASIC Quality - 71.3
Unigine Valley - 2723Pts, which is not a great result, some people here were able to go above 3000.
Superposition - 6000Pts.

The fan speed is BIOS unlocked, temps not going higher, than 74-78C

I tried increasing Power Limits with the KBT, but it has no effect at all. Tried different bioses, but they worked either similar, or just turned my Titan into the unknown VGA device.
So I have no clue, what to do. The only way, I see - is lowering voltages to save some power, but I don't think it will be stable at lower voltages and same frequencies. Other people here were increasing voltages, which has more sense in case of overclocking.
Or just let my Titan live in peace for some more months and go to the retiring pension))

_Adrian_ Following!

I'm dusting off a pair of Titan XP's and using them in a build with EK waterblocks.
If this gets me a tad bit more juice im all for it
