Anyone know somewhere with 7950 waterblocks in stock? I don't see any at FrozenCPU or Sidewinder.
Have you tried performance-pcs? They should have some.

I don't necessarily have a problem with Performance PC's support, what I do have a problem with is last time I made a $60 order I ended up with $60 in customs fees (I'm in Canada). I don't know what they do differently with their shipping, but I've never had to pay more than $10 in fees before. I suppose I will wait for FrozenCPU to get some stock.

Hey everyone, I have a bit of a dilemma. I have a Sapphire 7950 950mhz OC card (the one with the 7970 pcb). In Far Cry 3, with a 1235mhz core and 1660mhz mem at 1.163v, the first few minutes of playing the game, the gpu usage is fine, fluctuatung around 96 to 99. But then after a few more minutes, the game usage would sporadically change from 99 down to 80 sometimes and my game would stutter. My temps are perfectly fine, 55 degrees on core and 90 at most on vrms. Can anybody help me with this problem? On stock, it fluctuates less and my psu is powerful, 850watt seasonic.
Yes I'm running msi afterburner at 20% power limit. I'm also running a core i7 2700k at 4.2 ghz so I'm not sure whats wrong. Does voltage affect gpu usage? Do i have to maybe increase the voltage to feed more power into the core so the gpu can be utilized?Are you running +20% Power? If so it sounds almost like you are being CPU limited, what are you running?
Yes, voltage affects gpu usage. I've read of another [h] user who had gpu usage drops and it ended up being his psu. make sure your psu is good and can deliver steady voltage.
i meant the VDDC voltage, the core voltage of the card since my psu is a 850watt seasonic unit. i'm wondering if increasing the core voltage would get rid of the gpu usage fluctuates i have in far cry 3
Wow this is what I found out so far. When I increased the core voltage it didn't really make a difference, it just made VRM1 hotter. Anyway, the real odd thing is that when I decrease the MSAA to off, my gpu usage would go down to 80 and fluctuate from there having smooth fast gameplay. But when I put it on 8x aa, no matter what I do, it is pinned to a healthy 98 percent. Maybe you can give me some insight here, but I'm assuming at no AA, the gpu isnt being used fully just because my gpu has excess OC processing power when rendering FC3. But how is that possible? It's fricken FC3 for goodness sake! FC3 supposedly brings gpus to their kness right?It's worth a shot, your GPU temps are good (VRM's are a bit high though). Long as those VRM temps are in check try cranking the voltage up, you are safe till 1.3v so you have a long ways to go, put the fan at 100% and give it a test.

Hmm, yeah that doesn't sound right at all, the only case that would ring true is if you had a FPS limiter / Vsync, otherwise it would still use 99% of the GPU to get the highest framerates possiable. perhaps a driver issue is the cause? Is it only Farcry doing this?
mostly yah, except heaven benchmark kinda does it too, but that only ever drops down to 91 percent at worst at the same areas. Decreasing the memory overclock lessens the fluctuating in FC3 a bit. Would it be because my overclock is too high or something? I am really doubtful of that being the cause though, I have never heard of a case like mine happening to a gpu heavily overclocked especially since my temperatures are fine. Btw I'm using OSD in Afterburner to get all these usage numbers
so sorry I haven't replied in a while, busy with a few things.
No my clockrates are pinned at 1235 mhz and so are my memory clocks. I'll try your 50 percent power limit mod and see if it will change anything.
UPDATE: I don't have the number 14 at the 4th line, I have it at the 11th line in the registry, can you help?
Good luck! Most important part about the Accelero install, patience. Be sure to double check to make sure the heatsinks are not making contact with the board or any other things around them.Just picked up an Arctic Accelero Xtreme 7970 for my 7950. Heatsinks shown are the different types tha come with the cooler (I only showed one of each type). I cant hit 1200Mhz on my stock DualX cooling before the VRMs and core get hotter with the higher voltages, let's hope this helps
Hmm, give it a change and try, worse case go into safe mode and change it back.

Thats exactly the dilemma I had with the Dual X cooler. The only thing that was stopping me from having a higher overclock was the VRM temps and I have to tell you, the accelero xtreme does not improve the VRM temps a lot for the Sapphire 7950 OC.
Yes, it seemed to help a bit installing it between the VRM passive heatsinks and the rest of the cooler? Hopefully it helps a bit, because if it truly makes a tangible difference, I am happy out, I;d be able to go even higher than 1250 core.

I have also tried the fujipoly extreme pads with my stock sapphire VRM heatsinks with the accelero cooler. I found there is little to no difference in VRM temperatures
That's unfortunate. I wonder, if there is a gap between the aluminium fins and the VRM heatsinks, "joining" them with the thermal pad might help draw the heat from from the VRM
---> heatsink ---> thermal pad ---> fins. Or am I misunderstanding something? According to that link I posted, big gains can be had.
Ok tried it, didn't notice any difference. But here's what I noticed across all games:
When the fps goes below 60 fps in any game (aka, a very graphically intensive spot in the game) the usage is pinned at 99 percent and no less. When it goes above 60 fps, even in intense games like far cry 3, metro last light, and hitman absolution, the usage fluctuates in a range from 91 to 99 percent (it doesn't alternate between EXACTLY at 91 and 99, but within the percentages between).
If its not too much trouble striker, can you test this out with afterburner's OSD or gpuz? You've been a great help so far and I appreciate it but I really wanna know if this happens only with my card.
Installed the Arctic cooler. Stock heatsinks for memory and VRMS looked good. I thought I had lost a single aluminium heatsink, and was going to wait for Arctic to send me it so I could install them all (it turns out I hadn't lost it, but anyways). I installed the Accelero HSF on my GPU, leaving the stock memory, VRM etc heatsinks on.
I was very surprised. After an initial bump (wasn't mounted tightly at all, getting to 97 deg in sc2 haha), I was benching Heaven 1225core at 63 deg max after 20 mins (heaven maxed with Tesselation, AA, everything). The VRMs were good too. VRM 1 didn't go over 84 degrees, and stayed between 80 an 84 at max. This was with stock heatsinks too (albeit with perhaps marginally better airflow via 3 fans instead of two). Under stock cooling at that voltage/core clock speed I was hitting 90 and very slowly climbing. 84MAX is much more acceptable (I did optimise case cooling since then too though). I think what mainly helped was the fact that my core was cooler (by 15 + degrees- was maxing at 75-78 easily with an annoyingly loud cooler) which meant the card operated a tad more efficiently, which meant less juice running through the VRMs - and ultimately, cooler VRMs.
I hope to improve these VRM temps with the g1 glue + Arctic heatsinks and high quality thermal padding.
I could feasibly hit 1250, even 1300mhz on air depending on how my voltages scale.
As for noise? My case is super quiet right now. My PSU is the loudest at idle (and that is quiet) - Super-Flower Amazon 650 watt. The Accelero's fans are inaudible to 70% completely. Only mildly loud at 100%, indeed, basically as loud as my last system setup at idle!
Super happy with the buy, will be even happier if I can squeeze out a few more MHz with the thermal pads and Arctic heatsinks.
Side note, high ASIC cards (like mine at 90.6%), with their low voltages, seem to run a lot more efficiently than other cards. My card's stock speed is 950mhz core at 1012mv. Overclocked to 1200mhz core at 1112mv, my card wasn't throttling at +0% Power Limit in Heaven Benchmark.
VRM 1 gets hotter than 2, yes. It doesn't reach 90, though. It would probably reach 90 after 30 mins playing at 1200mhz core 1.112v (stock cooling). At what voltages/clock speed/cooling do you hit 90 deg on VRM 1.
As I say all that, my stats are general ones, I can't stay for sure if they apply specifically in high FPS situations, I should check that out.

Hmm, I haven't had these issues, then again when I do play like Far cry 3 and Crysis 3 I never get anywhere close to 60 fps (I play at 1440p with as high as settings as I can get FPS dependent). Generally I play around 30-40 FPS with almost max settings (one of the reasons I upgraded to a 780GTX). But when I go over such as in CS GO around 300 FPS, I never had it go below 99. I would check for any kind of VSYNC going on, thats the only way I could reproduce this. It has to be either that or CPU bottlekneck, I know you are at 4.2 GHz already but see if you can bump that up just for a test (make sure your temps aren't going to throttle your CPU too).
I will do the same later . Noted with regard to VRM cooling. I will play around with it to did the best option. Remember to max out heaven (Tesselation, etc). Can you do a bench at 1200 1.112 as well? I hope the thermal pads help then I got them this morning but they are delivered to my home address, I won't be there until the weekend.
I run my memory at 1700mhz but usually 1650mhz. Sure thing, i'll try 1200mhz and yes, I maxed out everything in the benchmark. I don't think I can run 1200mhz at 1.112v though, I have a slightly lower ASIC value (87.4%) than yours. I can run it at 1.131v no problem though.
