i7 970 - want more speed

post #1 of 3
Thread Starter 
Hello:

Even though I have read a number of items on the WEB, I still don’t understand all the whys and wherefores of the over clocking process.

I do video editing and have built a faster system (see below). The old system is an Intel Core 2 quad Q6600 that I OCed from 2.4 to 3.4G fairly easily but was limited by the memory speed.

I was able to OC the new PC from 3.2 to 4.0G as listed below with the help the online articles and reading posts on some fora. Prime ran fine for a few hours.

I know that hardware is not all the same. However, having read on the WEB of up to 5.0G with the i7 970, I thought I would give it a try but had mixed luck. The best I could do was 4.2G. However, while the PC starts and appears to run OK, Prime immediately fails with a x124 or an x101. I have the newest EVGA/NVIDIA drivers which appears to be what the 124 relates to. I previously had run MEMTest and it found no problems at 4.0G.

If I try for CPU of higher than 4.2G by increasing the CPU clock ratio, the system won’t boot. It resets itself.

Perhaps there is something else I can try? Changes to the video card or memory?

Another related question: As I can get 4.0G as listed below, what if any advantage is there with setting the BCLK frequency to 200 and lowering the CPU clock ratio to get the same CPU of 4.0G?

Thanks for any thoughts.

System:
GIGABYTE GA-X58A-UD5
BIOS version FD
Intel i7 970 (Rev. B1)
Thermalright Venomous X CPU cooler with Scythe 120MM 3000RPM fan
G-SKILL F3-12800CL9T-12GBRL (4Gx3) 1600 DDR3
EVGA 012-P3-1572-AR GTX570
ANTEC TPQ-1200 1200W
2 OCZ Vertex 2 OCZSSD2-2VTXE60 60GB SATA II - Boot Raid0
2 Seagate ST32000641AS 2T SATA III - Raid0
Windows 7 64 bit

Initial OC resulting in CPU at 4.0G - appears to be stable.
Enhanced Halt: DIS
EIST: DIS
QPI Clock: Auto (5.76)
Uncore Clock: X20 (3200)
BCLK Freq: 160
X.M.P Profile 1
(Result in memory settings per G-SKILL package)
MEM Freq: X10 (1600 1600)
CPU Vcore: 1.25
HPET mode: 64 bit
ERP: ENA
Smart Fan: DIS

Changed the following - runs so far except for Prime. CPU Clock ratio any higher won’t boot.
CPU Clock Ratio: 21 (4.2G)
QPI Clock: Auto (7.2
Uncore Clock: X16 (3200)
BCLK Freq: 200
MEM Freq: X8 (1600 1600)
CPU Vcore: 1.3
QPI/VTT voltage: 1295

What are you using to encode? What are you encoding from and to? In most cases, overclocking will not help you in encoding videos.

I use Sony Vegas for MPEG2 and AVC. DVD Architect for DVDs and NetBlender DSA for Blu-ray.

When I updated (a while ago) from 2 to 4 core, I noticed the difference in render time. OC of that system decreased render time as well.

Thanks.

PS: I didn't think there was such a thing as too much speed?. (G)
