Hello FtW

i did the IBT test with all thread and 8 threat with no differences.
Every thread worked 100% in booth cases

please, someone can tell me what is the power draw on 2600k+580 or/and 2500k+580??
I really like to compare with SB, because all people says that this new 3820 is a monster eating power, and its very hot

i did some test with my wattage controler

Idle: 124 watt
Prime95: 234 watt
IBT: 244 watt (more than prime95!!)
3d Mark vantage: 360 watt (i think it will be max load of entire system)
unigine: 349 watt (i think it was at stage 19)

This was tested in Watt, POWER FROM THE WALL (typical 220-2300vac)

vcore: 1.248v max
Speed: 4.300mhz HT ON (in idle speedstep down to 1.200 and 1.016 vCore)
Gtx580: 815mhz (without change vcore)
PSU: 900w GOLD
Max temp reached with prime and IBT in the hottest core: 55ºc

55C maximum in IBT, and you believe the people that are saying it's hot? Yes, I agree that this chip is a bit power hungry, but hot is one thing it's not.

Edit: I think this thread will be of more use.

post #386 of 6508
hello mates

i think the main difference in watt between 3820 & 2500k is HT ON

i found a link in HardForum with a guy who has a 2600k + 7970
Code:
7970 OC + 2600k OC - Power consumption + Temperatures
Today I bought a Power Meter so I could test my computer power consumption.
Cpu 2600k @4.5Ghz

Idle: 7970 stock 350/1375 = 155W peak
Idle: 7970 OC 400/1600 = 190W peak

Playing BF3 eyefinity 5760x1080 OC 1200/1600 = 430W peak
[B][SIZE=4]
CPU TEST: Prime 95 Torture test = 270W peak[/SIZE][/B]
CPU + GPU TEST: Furmark Burn In test + Prime95 Torture test at same time = 535W peak


Temperatures:
CPU = 42C peak
[B][SIZE=4]CPU core = 52C peak[/SIZE][/B]
MB = 26C peak
7970 = 84C peak

I did this test to find out if a 750W power supply would handle 2x7950 or 2x7970

Pc specs:
Intel I7 2600K @4.5Ghz/1.28v
Asus Maximus IV GENE-Z/GEN3
Sapphire HD 7970 3GB GDDR5 @1200/1600 running eyefinity 3 monitors 5760x1080
Corsair 16GB (4x4GB) DDR3 1600Mhz Vengeance LP Memory Kit CL9 1.5V
Corsair 120GB Force 3 SSD 2.5" SATA-III
Western Digital 1TB SATA-III Caviar Blue - 7200RPM 32MB Cache
Western Digital 500GB SATA-II Caviar Blue - 7200RPM 16MB Cache
Corsair Air Series A70 - Dual Fan
OCZ ZS Series 750W 80+ Bronze PSU
Pioneer BDR-206DBK 12x BD-RE
Corsair Carbide 500R Black Case (with 5x 120mm fans + 1x 200mm fan)
http://hardforum.com/showthread.php?t=1674095

i don't know what would be the difference in Watt about GTX580 & 7970, but in Prime95 i assume both graphic card are in idle state and their power consumption is very similar.

Ive just updated to the newest bios and I had to increase cpu voltage to 1.420 from 1.40 for keeping my pc stable in intel burn test.
Anyone the same exp?
It is for 4,75Ghz = 1.420 Is it still 100% safe?
post #388 of 6508
i think it would be safe if you have your temps in range.(i dont hear nothing about degradation in this chip until now)
but personally i will be up to 1.35 or 1.4v......

but it's very strange with your new bios needs more Vcore. can you back to the older bios and check???

That is a lot of power. Maybe my chip is excellent but it is rockstable at 4.87GHz@1.368Vcore.My RAM is 1.65Volts so maybe higher RAM voltage will give you lower Vcore?

well I dont know what "RAM" item do you exactly mean, but I turned on EPU power saving on and changed VTTCPU voltage from 1.100 to 1.150 and now
its working for 4,75Ghz at 1.375V. So its progress!

//Well not, now Im testing intelBurn test couple hours after and it works for 1.395... Strange. MAybe depends how my cpu was sleeping..rolleyes.gif
