21) Message boards : Number crunching : Benchmark results - times wanted for any hardware, CPU or GPU, old or new! (Message 61130) Posted 15 Feb 2014 by Dunx Post: No probs on it being o/ced :), just for the average 5 they need to be run at the same clock speed, otherwise the result is meaningless. Only 75% GPU util.? Did MW not have a dedicated CPU core for the 5 averaged WUs? Yup ! Always feed my babies properly.... unless the GPU really isn't using over half a "core".... HD 7950 @ 950 GHz - around 120 seconds.... dunx P.S. If the stupid R9 didn't have sticky-outy heat-pipes it would fit in the damned PC ! ! !

Btw I asked you this a few days ago :- Btw I just had a quick scan of your valid 213.76 cred WUs & some were down to the low 500s. Was the time you gave with the GPU at nr. 100% load? Mikey So any spare C2Qs or 5850s? ;) Also, you never did confirm if the results you gave for your grx cards were at stock MHz, are they? Sorry work gets in the way of my fun.... PSU is fine, but the Motherboard isn't.... only a GTX 480 will work ( bulletproof build quality and it's hot anyway ! And very noisy ! ) The GPU is around 75% utilisation, CPU is down at stock clocks for stability ( used to be at 4GHz 24/7 ) variation will be due to SkynetPOGS or MW CPU WU's (IMHO). dunx P.S. It's more likely that the first few Wu's were run at stock clocks, but as I'm an OC addict.... ( Sorry ! )

24) Message boards : Number crunching : 4x HD7990 in one PC? (Message 61086) Posted 11 Feb 2014 by Dunx Post: I think they are just seeing the added latency from a PLX type interface, the native x16 slots are fine ( up to three in use), but add a fourth or use seven single slot GPU's and the interface hardware shows it's delay.... IMHO, not many BOINC projects require "gaming" levels of bandwidth. Anyway hope to find out within a month or two ! dunx P.S. In general they saw about a 10% shortfall, hardly PCI-E x1 performance....

(Message 61028) Posted 9 Feb 2014 by Dunx Post: GTX 480 @ 750 MHz = Average of 520 seconds.... HTH dunx P.S. Old PC is it set up right ? Too many inconclusive for my liking ? ? ? http://milkyway.cs.rpi.edu/milkyway/show_host_detail.php?hostid=561093
26) Message boards : Number crunching : 4x HD7990 in one PC? (Message 61027) Posted 9 Feb 2014 by Dunx Post: I have a pair of Asus X58 boards here - both with burnt out ATX 12V pins.... P6T6 WS and P6T7 WS, neither have additional PCI_E connectors for the GPU's - but the X79 now does..... dunx P.S. I just bought a short extension lead and soldered the female half to the board, and the male half replaced the burnt out ATX connector on the PSU ATX lead : - ) P.P.S. GTX 480 and three GTX 460's, VS HD 5870 + HD 7950..... now added a R9 280X !

31) Message boards : Number crunching : What different tricks do you guys use to optimize your system performance? (Message 47476) Posted 10 Apr 2011 by Dunx Post: I use "Process Lasso" when messing with my system... You can assign CPU affinity and process priorities to suit. I.E. I have four GPU WU's serviced by 4 HT cores. And four MW CPU WU's serviced by 4 different HT cores on my PC. HTH dunx P.S. Also allowing one core to be busy will enable turbo-boost/speedstep on an i7 cpu for example.
