Nvidia 355.60 drivers and SLI workaround will allow up to 7916 vram usage combined and no stutter

[digsgravy]

So, I took some shadow play vids for the 970 SLI stutter, its not that bad, just some frame drops and slow down, although it can do better. So I clean uninstalled the ROTTR game ready drivers and installed 355.60 nvidia drivers. Whats special about these drivers is that it seem to allocate all the vram of both cards; so a total of 7916 MB of VRAM like cod detects. People in forums and tech sites were telling me it was a bug and it was probably displaying the combined vram although it wasnt really allocating it. Long story short, I did extensive testing and recorded metrics on games and it looks like its allocating vram. I installed the 355.60 added the ROTTR executable to the 2013 tomb raider invida inspector profile and did the SLI FIX for ROTTR. What happens is that VRAM usage goes to 6900-7100 MB and there is no slow down and or drops in fps like the game ready drivers and actually FPS average is up. Nvidia quietly reverted back the code in the later versions and although I tried to raise awareness, it was overlooked, What it shows is that combining vram is possible and NVIDIA intentionally limits thier cards through drivers.


Here is a vid with the 361.75 Game Ready Drivers notice vram maxes out at 4070 MB

I will post a vid soon of 355.60 driver perf and vram usage. gg

Thats stock.... Ive pushed my Phenom II to levels far beyond others, Im the fastest Phenom of my class rated on 3dmark. Im showing what an old cpu can do if you just overclock it vs the newest and greatest i7 cpu's at stock clocks which most people stay at.

My CPU Physics Score and Combined, http://www.3dmark.com/3dm/10247639?

My PC is better then 86% of others and would reach 99% if i used a 2nd 390x gpu...

err . a combined score is kinda irrelevant when you're talking about CPU's. It's highly doubtful that a 30% OC of your CPU pushed it's 3dmark ratings from stock 5040 to anywhere near 10k.

The i7 2600k released in 2011 and was over 400$ and its stock speeds are just a little over 2k more then my stock phenom.. I could care less about 'efficiency' if i get the same performance as a new 400$-500$ intel chips.... Once you reach around 8500 physics score in 3dmark you can play pretty much all optimized games with high fps with a high end gpu and im past that. Lowest fps in BF4 with 64 players is min 72 fps avg is 86 all maxed @ 1080

You won't cool some heavily overclocked 125W TDP CPU that easily with any cooler - that goes for Intel as well. Besides mainboard requirements and electricity cost.

December 2010, or january 2011 - not that much of a difference. Though 2k more than your stock Phenom, that's a solid 30'ish% more. Not really minor. In the end you get what you pay for, no?

Why would you require a 400-500$ CPU, 150-200$ one gets the job done just as nicely.
But hey, i can always buy some old Intel as well, then OC the crap out of it, if i even have to, and then post benchmarks. Your Phenom is nothing special in this regard.

BF4 is properly multi-threaded at least. Run your CPU in stock clocks in a more heavily single-threaded game - sadly so many of those around - and you got quite a bottleneck.

You don't care about efficiency, the rest of the world certainly does. And that doesn't even include newer features.
Had a dual E5 around for a while, for fun. Fancy things easily outperform some puny Skylake i7, but that doesn't mean it's a viable option for everyone.

I have the testing proof.... And a combined score is the most important score of all.... It will show you how well your cpu is pushing your high end gpu... I did far more then a simple tweak the multiplyer for more cpu Mhz.. I heavily overclocked my NB which benefits Phenom II's to an extreme... My stock NB is 2000 Mhz and my OC NB is 3188 Mhz... Why is it when intel people hear about such and such intel cpu reaches a good xyz score they scream ya so gud intel rocks! But if an amd cpu reaches at or near the same its, No that cant be right amd bad 3dmark must be wrong!....

I use a closed loop corsair 240mm liquid cooler which is not the best i could get, i could fit a 280mm with 140mm fans if i needed to. Phenom is power hungry at these clocks it needs 1.6 Volts, also getting an older I7 would be the smartest thing most intel fans could do since intel charges insane prices. Also i do run a lot of games that are single threaded and they work fine with high fps, just look at my games and pics... i think staying above 70 fps at the absolute min at max settings is good enough dont you think? Anno 2070 is known for its terrible single threaded performance and i play it just fine with huge city's at 60-80 fps

So that's 100 bucks for the (noisy) cooler, approx 50 extra for the mainboard, some more for electricity, and being lucky in the silicon lottery.
And your single-threaded performance relies on this heavy OC, no?

Not sure what an Intel fan is, and i wouldn't buy Skylake either.

Edit: hope you get my point. Just for arguments sake anyways ^^

OP has no idea what he is talking about or how SLI works. SLI mirrors the memory on each card, just like a RAID array. It doesn't mean you have double the VRAM. This is a restriction of the technology, and thinking that some random nvidia drivers secretly implement it is beyond fooling yourself.

My Phenom is a little faster then a stock i7 4770k i think thats pretty damn good for a cpu made in 2009 and it also reflects in real world game fps.

I scored over 12000 with my 3770k

Look I know very well how SLI is suppose to work. Please explain how this driver 355.60 uses more vram than the 4077 MB vram in the video in my first post?I will upload a vid once I get shadowplay to work, however look at the vram usage in the screen shots its 6100 -7100MB, and it also plays alot better, higher FPS and no stuttering or major fps drops. There is a switch that was left in this driver, which Nvidia promptly removed. Because it works, its using more vram but within the pooled value and plays better. There is about 8GB of system vram being used also with this driver for Tomb Raider.

355.60 is a bugged driver. It has a memory leak, reports false numbers and over time crashes the system. The issue was hotfixed with 355.80.

This thread gave me cancer. O_o

The memory leak was with BF4 and maybe another game. 355.62 stopped the memory leak in BF4 at least. There is not a memory leak in Tomb Raider and no crashing and the numbers being reported are not false. Its detecting 8GB vram and using that and system memory and Rise of the Tomb Raider runs a lot better. Tomb raider is usign 8GB of system memory. I have it working on my gaming system and the point of the post was to help out other SLI owners. Its a bug but it works as an advantage for ROTTR. rekt

lol wut? phenom 1100t stock compared to i7 980 stock? no way it's possible.

[CMyTA]

http://www.3dmark.com/fs/3505391 here is my old result with pc i no longer have, i had stock i7 980 and it's beating your supa dupa very high overclocked phenom like a baby

[CMyTA]

you can try 5ghz and maybe your phenom will show the same physics score as stock i7 980, but it just lolz pretty hard

Know what you mean, i wish it gave these dumb morons spouting technical fallacies cancer instead.
