sluggish
hi, all.
Well on the 5/5 i purchased an i7 system with almost identical sluggishness.
Specs:
Gigabyte UD4P
920 CPU (stock heatsink)
Corsair 6GB DDR3 (TR3X6G1333C9)
Corsair HX1000 PSU
Palit GTX295
3x Seagate hdd's (sata250,320 and IDE160)
OS: XP Pro32 on the 320, Vista ultimate64 on the 250, IDE is backup.
This system has caused quite a lot of grief.
First system wouldn't post; the memory was stuffed. one stick of the Corsair was faulty. kit replaced under warranty.
Then, again system wouldn't post.
This proved, believe it or not, to be the IDE hard drive rack. The PSU detected a short and refused to allow a power up. Chucked the rack, and voila!
Then BSOD at system install(about 45x's).
old version of XP Pro....it was pre SP1 on the CD i have to admit, but the O/S was updated to sp3. I slipstreamed SP2 to a new CD but
the key was just too old ....apparently.
Another copy of XP and, that key wouldn't work either????
I have to admit at this point that i was attempting a system repair (re-write HAL) from an Athlon 754 ddr1 system on that hard drive, so i should have expected problems. 754 to i7 hmmmm...
(I did prepare Windows in safe mode by removing all relevant drivers and running a driver removing utility on the 754, so technically i gave myself the best chance of success. technically not actually)!
I eventually got it up and everything is working.
As the days go on, it starts taking 5 full minutes to load up XP.
Adjust page file.....some difference but still generally poor system performance. slow to open anything, ie control panel, administrative tools, DxDiag etc. ran a non windows defrag utility, better.
ran the old single threaded 3dMark03 and got 72000 3dMarks.
(not too shabby compared to the old 754 9000 3dmarks when it was at its best).
Ran it again and crash, and once again, crash also.
Next i started playing with bios settings and got nothing but POST errors.
This was a hint though i didn't know it at the time.
Next i used the windows Gigabyte Easy Tune6 utility (QuickBoost 1 ie: 2.8Ghz) and got POST errors.
whipped the CPU heatsink off for yet another inspection and all looks OK but on closer inspection i see some thin(er) spots of the OEM paste.
Go out and purchase some $10 Antec Formula5 Silver Thermal Compound.
I clean the CPU and heatsink and apply the paste exactly in accordance with the instructions.
This Antec paste appears to be almost identical to the Intel paste in both colour and viscosity.
The application procedure consists of applying 1/2 the size of a rice grain of paste to both the CPU and the heatsink. Next you spread it around by putting your finger on the inside of a clean plastic bag.
This sounds simple, but, the paste is so thick it takes some time. gentle but forceful action spreads it. clean up is with a single edge razor.
I can immediately see much better coverage, and, as it is applied to both surfaces seems to be a more efficient solution.
boot back up....still the same.
Next i play FSX with all settings turned up on full.
I have a saved game where i am conducting an instrument approach into San Fransisco Intl in a 747 near max landing weight at dawn at about 28deg ambient. there are about 50 other "heavies" under radar control (sorry for the wankie jargon) and thunderstorm activity. There is filtered streaming light and shadows, mist, lightning, intermittent showers and a rising sun. The city is still lit up and the traffic on the ground is set to 100%. the draw distance is 60 miles and moderate turbulence. wing tip vortices stream off and on as the aircraft passes through this turbulence. res is 1280x1024@60htz on 32 bit XP pro.
Now with all of this load the frame rate is pretty poor around 8-15fps.
I re run then notice an increase 15-25's. and again etc 3x's 15-25's.
back to windows and system idle for about 15 mins. open easy tune and notice idle temp of 27-29deg. This is fully 10deg less than before.
Next i notice the system noticeably more responsive.
boot to bios turn QPI link speed to full.
system seems to be more normal.
a number of factors MIGHT be at play here:
1) i think my ram is rubbish (though i could be wrong), and i might say the same for the board as well.
2) I find it alarming how much force is required to close the CPU lever on my gigabyte board. this force MAY cause some localized bending of the board.
My lever actually bends in the closed position.
The retention mechanism for the heatsink combined with a possibility of some potential for localized warpage in the CPU area may cause less than ideal motherboard to CPU pin contact and/or heatsink/CPU contact.
3) this less than ideal contact may be addressed by application of a high quality Brand name heatsink paste.
4) a burn in utility could be good to "activate/melt" the paste and to burn off any oxidation of system contacts...ram, vga cpu etc.
5) i might be completely wrong about the warpage causing this but i have noticed that after the system gets hot my computer has been getting better, and the sluggishness generally less each day.
6) i wish i had spent $70 and got the store to set up my system. it would have saved 3 240km trips to my store.
I installed Vista 64 on the other hdd and all seems to be good, except that absolutely nothing seems to work properly with the O/S...nothing opens, no windows fix utilities open, side by side errors on just about everything, unzip utilities won't work. looks nice but what a piece of ****.
this is my first vista experience. Crysis plays well though and looks totally amazing. my son likes shadowrun and it looks good. Vista experience is 5.7. cpu, ram, vga 5.9 and Seagate Sata 5.7.
My Vista experience however, is 0.
I've read GTX295's are bottlenecked by 920 at stock speed so in coming weeks i'll hook up my LCD and re try the o/c at 1600x1050.
cheers,
Paul.
