Time for IAO Cooler?

I wish I could......It´s just cost to much for my "tiny" budget.....

I don't understand why you people run uncore high, and yet such low DDR.

Almost every DDR3 chip manufactured after 2010 is capable of at least 1800 MHz. Later ones can hit 2400 MHz.

For example, G.Skill Ares F3-1333C9Q2, got this kit to work at 2350 MHz, 10-12-12-31, 1T, 1.64v. Can also do 1600 9-9-9-24, 1866 10-10-10-26, 2133 9-11-11-31.

 

[Zyll Goliat]

Don´t forget that Uncore is primarily the memory controller but also controls the L3 cache, and faster L3 cache performance can give you performance gains in applications.....

 

[FilipM]

As I have said, ram speed (anything above 1600-1700) is useless on an X58. Uncore speed always brings more performance on the table.

PS. What @Zyll Goliath said.

 

[FireFox]

I don't understand why you people run uncore high, and yet such low DDR.

For the simple fact that this Machine is used for testing/Overclock/fun and not 24/7,that said if the Ram runs at 1333 or 1867 for me it doesn't makes any difference.

 

[Regeneration]

Overclocking RAM is part of the fun and isn't difficult. Some new apps and games benefit from high bandwidth. 20GB/s vs. 30GB/s isn't useless. One of the greatest features in the last 1366 CPUs is the ability to run DDR at crazy clocks... It was impossible on Bloomfield. With stock DDR 1333/1600 clocks, Westmere is a bit slower than Bloomfield in memory bandwidth.

Then you should look a few pages back where i have posted my ram running at 1800MHz+ and 1900MHz+ and of course it's not difficult because i do it often.

For example, G.Skill Ares F3-1333C9Q2, got this kit to work at 2350 MHz, 10-12-12-31, 1T, 1.64v. Can also do 1600 9-9-9-24, 1866 10-10-10-26, 2133 9-11-11-31.

And my question is: what was the CPU clock speed?

 

[Regeneration]

And my question is: what was the CPU clock speed?

4.3 GHz (166x26) 1.30v, QPI 3984 MHz (8 GT/s), Uncore 3486 MHz, VTT 1.30v, on air cooling, max CPU core temp was between 68-72 under IBT. Other voltages (ICH/IOH/CPU PLL) were left at stock.

With an overclocked GTX 970, 3DMark FireStrike scored around 11,500 - 12,000.

That configuration gave the highest performance in games without extreme voltages. I always prefer to keep longevity. As I said before, the best BCLK range is 16x.

And what was the exact Ram speed?

 

[Regeneration]

And what was the exact Ram speed?

2324 MHz 10-12-12-31, 1T, 1.60v on triple channel. AIDA64 copy benchmark was around 27 GB/s.

Which CPU?

 

[Regeneration]

An old Xeon W3680 that been in heavy use for 5 years.

That's why, because the 5690 at multiplier X26 and BCLK 167 doesn't give me more than 800+ and that's at 4.5GHz.

Screenshot:

 

[Regeneration]

1. What do you mean doesn't you give more than 800? Can't you adjust DDR multiplier?
2. Its better to have QPI higher than uncore. I noticed you run them at 1:1 ratio. 500 MHz higher is optimal... but may require more VTT.

Here are the bios's settings for that overclock, you tell me what to change.

Edit: that is for a 4.5 overclock not for the 4.2 i am using right now.

Well...It´s happens that I also have GTX 970.....and with all talk about slow RAM speed I checked my results in FireStrike so my best score is:

Well How´s that exactly worst score from yours with faster RAM speeds?And how much in %?
PS. MY CPU Here Was OC on 4,118GHZ
GPU core was on 1519Mhz

3DMark is a bad example, faster DDR doesn't reflect there. Post specs, including mobo.

waiting for your answer.

better?

Srry but 3DMark was your example.........You have my specs on previous page also....but here you go:

I'll post detailed DDR timings when I get home.

1. Increase PCIE Frequency by 2-3 MHz, it helps stabilize random POST failures with high BCLK/QPI.
2. If you use static vcore, disable EIST, it doesn't work, no voltage reduction. C-states work up to BCLK 162.

 

[johnspack]

Getting ready to put my x79 xeon under linux. Hope this goes well! Kubuntu to start....

 

[Regeneration]

Srry but 3DMark was your example.........You have my specs on previous page also but here you go:

It was a reference... besides, you have a better motherboard, and higher GPU clock.

 

[Zyll Goliat]

Yep...but also my CPU speed was way lower then yours..........anyway my point is still the same.... RAM speed does not effect that much overall performance in every day apps.....the difference is mostly negligible......

 

[FireFox]

Increase PCIE Frequency by 2-3 MHz

But but i am using a zotac 610

disable EIST, it doesn't work

What doesn't work
