i7 950 running hot on Silver arrow - Page 3

post #21 of 57
It will just be your core voltage... which will probably read 1.41 if you stated your voltage correctly. It won't necessarily be max voltage as much as just "set" voltage.

Getting a machine built for you is no fail- looks like you've done some research and at least had them put some good components together. Now then- just to get that OC cleaned up a bit (lot)...

I'm not familiar with Hardware Monitor, but I've heard of the program and I'm sure it's fine to use. The 'current' value in the Hardware Monitor screen should be your VCore voltage. It's normal to see lower voltage in Windows than in BIOS, called VDrop, as well as lower voltage when the CPU is under load, called VDroop.

And no, the 'max' value is not your VID. With the iX series processors you can't see the actual VID, but you can estimate it using the method that I described in one of my earlier posts. VID does not change for an individual CPU. It is stands for Voltage Identification Digital, and it's what your motherboard uses to determine how much voltage to give your processor on the AUTO setting.

If you want to see the temperature of individual CPU cores, then you can use CoreTemp.

Okay so I started from the begining.
BIOS set to default

prime95 run for 5min

temp: idle 32C
temp load(pr95 smallFFT): 55C
CPU VCORE value under load: 1.23V
CPU VCORE idle: 0.95V
CPU is @ 3.2Ghz, I think BIOS default settings enables turbo mode.
RAM is set to 1066Mhz default, cas Latency 8.0 clocks (according to CPUID)

are these values normal?

It's 2AM here in South Africa at the moment, Merry Chrismas to all of you!
I will be overclocking very soon, just need to get some time on my hands.
post #24 of 57
Those values all look normal. Turn off Turbo Mode and SpeedStep/EIST. Note that when you start increasing your BCLK, the RAM speed will go up, so set the divider to the lowest option. This will prevent the RAM from interfering with the CPU overclock.

Keep at it and keep us informed, and we'll help out as much as possible.

Okay, so restarted again, but my VID has changed for stock.

Sorry I'm taking long now

okay,
reset Bios, I disabled EIST, C1, turbo mode and spread spectrum settings.
temps idle:31C
temps load prime95 small FFT: 55C
ambient temp: 29C - 31C getting pretty hot here in South Africa( not ideal for overclocking) but fans are on full blast
CPU VCORE: 1.168 (or 1.17 from CPUID) ,so VID for stock has dropped

THIS is what My BIOS looks like, IGNORE the settings it's not mine(I copied it from a thread), just for a easy reference so that I know what to change.

Okay, now for setting the stock settings before I start overclocking, Im following your guide kremtok

BIOS settings:
CPu voltage: 1.17 (my VID stock settings)
CPU ratio , thats multiplier right? and I need to set it to 23.0 right?
RAM speed is 1866Mhz and cas9 from manufacturer's
RAM voltage is that DRAM voltage? how do I set the divider?

EDIT UPDATE**
overclocking,
CPU @ 3.6Ghz
Vcore: 1.16
CPU ratio multiplier : 21.0
QPI/DRAM core voltage: 1.25
Vdimm: 1.65
TEMP load prime95 10min:56C

**NEXT UPDATE**
got ahead of myself and changed Vcore to 1.25 and CPU @ 3.8
load temps: 60C

Im at 1.38 vcore according to my hardware monitor for my 4ghz oc. but i set it to 1.32 in bios....you wont run memory up to 2000 unless youre base clock is set high with a low multiplier. 1600 is all anyone really needs for i7s

they should have sold you ram that fit with the silver arrow, not moved the fans up high on the cooler to compensate for memory "cooling" fins that are little more than useless bling.

i agree that the fan positioning won't matter at 4ghz, but if you ever want to push that speed to the limit, you'll have to jack the voltage back up to 1.4v... and you'll want all of the cooling air you can get.

check the positioning of the rubber vibration dampners on the cooler... the fans are riding high, but they should not be making contact with the cooler, only rubber.

i don't necessarily agree with the general sentiment out here that the shop gave you a "bad" overclock... what people aren't recognizing is that you got a *reliable* overclock, because of the high voltage and relatively low 3.8ghz cpu clock... reliability is one of the primary duties of a computer retailer.

great thread, tho, with some xlnt advice.

I've just taken a look inside and the fans on the Silver arrow arent set up high, just placed like this

I got AirFlow fans with the Cosair DominatorsGT, would it be a good thing to install them?, shop owner said RAM fans are very loud thats why he left them out.

They built a good PC, very nice cable mangement, but their OC was quite fast and temps were running too high for me.
post #29 of 57
i see, they put the fans on the pull side, instead of the push side.

i think that fans typically cool better when pushing(?), but in that specific scenario, i can't say for sure, i've never tested it... fans on either side of the cooler will be great for your use, i'm sure.

the temps that you measured with prime95 will never be duplicated in the real world, so it's largely irrelevant... you typically test with prime95 and such only to establish a stable baseline, and that's it, so feel free to overclock to the moon.

it's normal to be paranoid of cpu temps, but if you ever burn in indigo extreme thermal material at 100 degrees, you'll understand that running cpu temps even in the 90's are not an issue.

outside of the ram fins, i like the build that they did for you, there are some quality parts in there, and i think that the shop was right to leave the ram coolers off.

If I look at this review I see little difference in pulling or pushing

Your probably right danimal, but I'm making this a challenge for myself, try get the i7 950 to 4Ghz with 68-70C Full Load
