HP 820 Tower - RED EDITION

[Tom Lowe]

It's dual processor Xeon 3.21GHz with 8 cores on each processor, which gives you 16 cores total.

Can Xeons be overclocked?

Can Xeons be overclocked?

Not really.

[Tom Lowe]

Why not?

[Jeff Kilgroe]

Why not?

The internal clock multiplier is locked, all you can do is tweak the external clock frequency and voltage. Few Xeon motherboards have the ability to do even that, for the new E5-2600 series, only the ASUS and EVGA boards have the ability. It's hard enough to keep a CPU like the 2687W happy and cool under load, I'm not about to start ramping up voltage and external clock speed. Hard enough to find proper RAM fast enough for it as it is, so overclocking the RAM or trying to find faster ECC registered RAM is like hunting for unicorn turds.

One thing to watch though is the upcoming generation of 22nm Ivy Bridge Xeons, which are in sampling and OEM testing right now. Less than a year away from launch. The current samples are all shipping with unlocked multipliers and they consume a lot less power. First time ever that Intel has shipped Xeons, samples or otherwise, with unlocked multipliers. We'll see what happens....

Interesting. Thanks.

Overclock or not, it seems to me that sixteen 3GHz cores beats six 5GHz cores for CPU-intensive tasks?

Yes, provided your software uses all the CPU cores. The Xeon CPUs also have larger cache and other features that help increase performance too.

So am I reading Big J's 1st post correctly....

There will be a builder to add whatever you want. RED ROCKET, CS6, and all drivers etc are pre-installed, starting around $10,000.

Sample Build :

HP Z820 (16) 3.21GHz Cores, Liquid Cooled, 32GB 1600MHz Quad Channel Memory, Nvidia Quadro 5000 GPU, RED ROCKET, (1) Internal BluRay/REDMAG Reader, 300GB, 2.5" 10K SAS 6Gb Boot Drive, HP 3-3-3 Global Warranty on HP Components (does not have: Any RAID volume - these need to be added by TEKSERVE or ProMAX)

Surely this above spec is more than 10k? Or am I just looking at things with UK eyes where we always seems to get shafted on computer stuff.. (I have got used to paying 1 to 1 dollar to pound)

Thanks

The specs on the sample build is certainly above 10k. That price is most likely for the entry model; the tech specs can be found on the Promax website:

I read the Anandtech review of the new retina Macbook Pro...

You should have also looked at the color gamut of the display. It only covers 66% of AdobeRGB. Not good at all.

Has anyone received any price quotes for these? Curious to know what a typical config actually costs.
