Yeah, that's possibly it. And maybe it's also that it takes FB-DDR2 as well. And put in context with the X6 it isn't too bad---a third more cores and two thirds of the clockspeed for the same output isn't bad. I can't see getting that high of a speed--the multiplier is only 7.5x, so I'm limited there....
But yes, the 2700k I have absolutely dominates--I think I got close to 7k PPD before I set up the GPUs.

I sold the E8400 system today, so I'm down about 1.2k PPD for now. But I'll be purchasing a HD7850 or HD7870 within the next ~36 hours, so that will be a cool boost :toast:

Hopefully you can get that stable. At least running Memtest is easy and new RAM is pretty much dirt cheap.

Right now the ram is running at SPD timings, but I have a cheap set I can throw in there if needed.

Yeah I tried updating to the 13.1's last night. Went over like shit in a fan. System restore to the rescue. I had all kinds of crazy crap going on and it would let me uninstall them. Said screw this and hit restore. All is good again.

The Cat 13.1's are now gone and replaced with 12.11Beta's I'm using on the other rigs.

@t_ski-Try CAT 12.6 if you keep experiencing issues with that PII/Vista rig. I've found that one is super stable for all of my gpu crunchers. I may get a little more ppd out of a newer version but I go with what gives me the least issues/best stability

Also, I've had issues with Human Protein Folding and Clean Energy Project wu's (errors/invalids- no crashes) with my Vista rig. I'm pretty sure it's the OS and not the hardware as it did the same with all different hardware setup.... you may want to take those off the project list for the rig if you start seeing errors with them.

Good to know - I'll keep that in mind :toast:

Okay here is what you need to do; find a large box and gather up a fair amount of packing peanuts. Put that system carefully in the box with the packing peanuts, and then send that sucker right to me.

After all the damn trouble and lost money I went through to get this rig up and running? I don't think so... :shadedshu

I'd like to know the PPD of a HD 7870 Pitcairn vs. Tahiti Le, does the Tahiti one really gives more points? How a 7870 do compared to a 7950? Thanks comrades!

a regular 7870 will do 70-75k ppd (8-10 wu's running)- Ion runs the Tahiti model but I'm not sure of his ppd

Does anyone have any DDR2 RAM laying around they wouldn't mind selling me? Preferably two identical 2gb sticks because I have OCD... Thanks

My 7950 (10 WUs) paired with an slow i7 920 does 95-100K. It seems like IONs Le does around 80K but I don't know the history (down time, games and so on).

~80k or so on a stock-clocked i7-860

It's a shame it has to be 2GB sticks--those are expensive and hard to find. I can, however, supply you with basically as many 1GB sticks as you could want....

This is one of my dedicated crunchers--it just sits on the windowsill and runs WCG 24/7. Usually I pull about 80k PPD from the slightly OCed HD7930 on a stock-clocked i7-860 (I've had issues with this setup, so it stays at stock as to not disrupt the GPU). I'm running 8 WUs on it ATM each with 2/3 of a CPU thread.

I'm actually only getting about 85k PPD from the HD7950---I need to do some reshuffling. Ideally I think I'll put the HD7950 in the i7, the HD7930 in the Xeon, and the HD7850 in the i3.

Sounds like a good plan. I run my 7950 at 1100 MHz and the CPU at 3.4 GHZ and it does make an error or two but I think it is a driver issue. I doubt it is temperature related running at 52 C. Since it is my my main PC I noticed the "driver stopped working and so on" thing a couple of times per day. That generates 2-4 errors each time. BOINC Task tell my an error number but I can't find an explanation on the forum. I could ask I know....

I am afraid that the i7-860 at 2.9GHz won't be enough for the HD7950, but I'm sure it will be better than the i3. And I'm also confident that I can get ~3.4GHz out of it pretty easily :toast:

I still have my 870 @ 3.74 (170x22) @ 1.35v and it works fine.

Might be buying a 7950 (Gigabyte) this afternoon as I now have some money set aside. If I do buy it, I'll put it on either the 2nd 3770K rig or the 2600K rig to give it enough juice for 10 WUs. Might take a look on Anandtech to see if there are any good used ones but they are $300 new anyway.

You're going to buy two HD7970s? :eek:

That would be awesome!

Jstn7477 · Jan 28, 2013

Quite possibly, but still deciding because I love to blow money on hardware. I sure hope they don't run out of GPU work right after I buy them lol. I don't forsee the next gen GPUs bringing much to the table so I might as well pick these up and at the least end up with an awesome CFX setup if GPU WUs go away.

You'll know if I got them if I start getting 300K PPD next week. :roll:

Now Ion can buy a pair of ASUS Ares II 7970x2 cards :laugh:

FYI- I think Rad Ed has an MSI reference card so he may be able to let you know how it runs as far as heat, noise, performance, etc....

More output is always better, particularly when it doesn't pose an insurmountable risk to me

Thanks for all the information!
But for $225 I can get a HD 7870 Pitcairn, for $235 a Tahiti Le and for $240 2x 7770... What should I get? I'm hesitating between the Tahiti Le and 2x 7770...

For those prices and for gpu crunching use I would say the Tahiti LE (more SP- 1536 vs 1280= more potential output).

My own preference is the 7870 Pitcairn due to the chip being 100% complete rather than a cut down version of another chip...

Jstn7477 · Jan 28, 2013

I wouldn't bother with dual 7770s as a single Pitcairn is pretty much the same as having them. Plus, a bigger single chip is more suitable for gaming if it ever gets used for that later on. Not really a fan of Tahiti LE as it's just a broken Tahiti with 256 more shaders than a perfect Pitcairn.
