Just 'cause I've got this monster, doesn't mean I'm going to be able to run it for any period! My FX8150's are better on leccy and are rock solid o/c'd from 3.1 to 3.4...

I'm going to see how it goes with the monster, then decide!

Mamajuanauk,

You said you also have an FX-8350 right? I have been considering that chip for a crunching build. I have been trying to figure out (with little success) how the 8350 would compare to an Intel 3770. I'm not sure if I should buy it for $200 if the Intel is much better for $100.

Is there a benchmark or stat that pertains to the crunching speed on WCG?

Review and comments on the ‘New’ AMD FX 9590 CPU

This is not so much a review, more a look at how this CPU compares to the AMD FX 8350.

The test machine for both CPU’s were as above with nothing changing except the CPU & the fan speeds to combat the higher temperatures of the 9590

Starting with the baseline above from the FX 8350.

The ASUS web site shows the need to upgrade the BOIS so I downloaded and upgraded it. I did not the lower temperatures of the MB & CPU after the upgrade, however, this may have been due to the down time of the system, I did not run the system for too long, just enough to confirm it was stable after the BOIS upgrade. The lower temps were still obvious after about 10 minutes of running WCG flat out!

The machine was shutdown, power unplugged etc. the 8350 was removed and replaced with the 9590, having installed a new CPU the BOIS was updated with the correct default settings for the Processor, no other changes were made.

First test – confirm stability, initially with basic tasks, Firefox, Word etc. all opened fast and things were starting to look good. Opened ROG Ai Suite II, Corsair Link2, ROG CPU-Z, Core Temp & Speccy to monitor the temp, CPU speed etc. This returned the first anomaly, while Core Temp & Speccy returned the same CPU temp, Ai Suite (that comes with the MB) shows it a much higher. This required some investigation, resulting in the conclusion that Speccy and Core Temp were picking up the wrong sensor value!

Having confirmed stability and temperatures etc, I turned to ‘playing’ with the settings to see if this processor would stand and O/C’ing and how much…

Without posting loads of data, the answer was a resounding no! Using the Ai Suite Auto Tune option and manually changing the various settings from CPU ration, multiplier, to the various voltages nothing seemed to ne stable enough to run WCG for more than a few minutes before the dreaded BSOD!

On route I did make a note of some of the BOINC Benchmarks the highest I recorded, but not stable was:

28/09/2013 22:10:36 | | Benchmark results:
28/09/2013 22:10:36 | | Number of CPUs: 8
28/09/2013 22:10:36 | | 3450 floating point MIPS (Whetstone) per CPU
28/09/2013 22:10:36 | | 12618 integer MIPS (Dhrystone) per CPU

With all the crashes and BSOD’s I reverted back to default settings and a solid stable machine. I did ensure the turbo option was enabled within the BOIS, however, rearly have I seen any of the reporting tools showing 5Ghz for any longer than a few seconds, even when running BOINC flat out.

Power usage
This system now uses the following power at the given loads:

Idle = 250 watts
CPU 100% = 400 watts
CPU 100% + GPU 100% = 750 watts

The same loading as above was used, GPU’s & CPU were at default settings. Readings from Corsair Link commander

Temperatures
Idle = 38 C
CPU 100% = 60 C
CPU 100% + GPU 100% = 61 C

Readings from the Ai Suite II software

Summary
In summary I would say I’m disappointed with the overall performance of this Processor! Looking at the benchmark posted above for the other system (only difference being RAM) the 8350 @ 4.4Ghz benchmarks are more impressive than the 9590 @ 4.7Ghz with the fact that latter uses significantly more power, the old 8350 is better!

Conclusion
This processor may well O/C higher with someone more experienced and knowledgeable than I tweaking the settings etc. From my point of view it is no better performing than the 8350’s I have and uses more power to do it!

Dissapointed…

I’d like to hear your comments…

If you want another CPU see the FX-6300 or the Phenom 1405t at Amazon UK. Currently £82.68 and £78.59 both with a 95 watt TDP.

Your temperatures look good and you have one of the only 3 approved motherboards for the chip. So it is going unstable trying to boost it above the base 4.7ghz? That's kind of a bummer, maybe you can find someone on an AMD forum who would know what to tweak the voltages to.

I never touch/tweak the voltages because I don't know enough about them, have not read up on them. Probably because I have not had a true overclocking chip yet.

But I am in a similar situation with my i7-3770, it's a non-k chip but is still supposed to be able to overclock over the base frequency of 3.4ghz. Supposedly is goes to 3.8ghz turbo. So when I started WCG I turned my clock speed up, I noticed if I set it at 3.8, that it would go back and forth between 3.8 and 3.7. So I set it at 3.7ghz thinking that would be a little more stable since it won't move off 3.7 when set to it.

Well about a week ago I did several CPU speed tests, using different free softwares on the internet. Even though my clock is set to 3.7ghz, it's showing up on the speed tests as 3.492ghz. I have an AsRock H77M motherboard. So I don't know if its a problem with BIOS, or maybe the voltages need to be tweaked up too and not just the clock speed, I'm not sure.

I know it's not a cooling issue because I have Cooler Master Gemini S24 cpu cooler and used Artic Silver 5 thermal paste. The case also has three fans (140mm front and top, 120mm back). Once I put a GPU in there I'll add a 140mm side fan which I have but didn't install, don't think it needs it without a GPU.

Well here's hoping we can figure out how to overclock our chips!
