Any of you have had any CPU Broadwell ? https://www.reddit.com/r/hardware/comments/3meznc/design_defect_in_i55675ci75775ci75700hq/ I saw this thread and another over MSI forums where there seems to be a problem with some chips.

There's a known errata with frequency that produces those crashes:

Errata BDD95: Operating at (or above) P1 frequency may lead to Time Out Machine Check (P1 frequency is non turbo max speed, 3.1GHz for the 5675c and 3.3GHz for the 5775c).

But is it a hardware or software failure? I've read problems with tf2, csgo, dota (dota frown.gif ), this would be a no-no for sure concerning Broadwell. I'm sorry if the questions are stupid, this is my first build ever and I'm not sure how this problems are resolved,etc.

This is a hardware issue, but only occurs when using specific software and it's not reproducible problem (you might get it sometimes and sometimes not).

If this is your first build I suggest you to go for Skylake. Broadwell is a good option for people who already have a pc with h97/z97 motherboards, but in a first build, Skylake offers more performance and more futureproof components for about the same price than a first build with Broadwell.

I am pre ordering one of these but want to overclock it while underclocking the crystal well L4 cache.

Cant get an answer from asrock on the BIOS but appears Asus allows this.

All Xeons on the mainstream socket are locked. They are usually a cheaper alternative if you plan on not overclocking, though.

The only unlocked Xeons are certain 1600 series for the enthusiast sockets.

Thanks for the relues.
I have read for days now.
I have 2 x ASRock Z97 6 rigs.
My 4790 will become the spare as this chip will get the 2 x NVMe 750s and the 4790 gets the 951 M.2s.

I use odd applications where the high random seeks and transaction times are truly beneficial.

Great thread.
Glad its over for me finally.

I will probably underclock the L4 and stay with 3.7GHz.
Seems 2000mhz on the eDRAM is as high as it will go.

Be happy to try some of these benchmarks used here. Non gaming though.
Im shooting for 2400 voices of polyphony.

88 voices of polyphony equates to every note if a Grand Piano played simultaneously.

FWIW thhundreds oc thousands of 64k buffers are stored into 32GBs of DDR3L.
Each note on an 88 note controller triggers about 16 of these RAM Buffers.
They stream the rest of the audio from the dual NVMe devices.
SSDs were okay at 80k random iops.
But the Intel 750s hit upwards of 300k.

Those Dogs Will Hunt.

Just purchased an i7 5775C cpu off PLE's site here in Oz but now it looks like I have to get rid of my old 1.65v 2400Mhz Mushkins for a lower voltage 1.35v model.

For those that have already purchased a Broadwell, what memory are you using with it so it doesn't burn out the memory controller?

Officially, according to Intel, normal 1.5V DDR3 RAM is supported.

All desktop Broadwells support 1.5v DDR3 as well as 1.35v DDR3L.

DON'T.

Broadwell ram specs are exactly the same as Haswell. In case it doesn't run with 2400 1.65v, try to underclock and undervolt the ram, or simply run it at 1600 cl9 1.5v.

BRILLIANT because there is bugger all decent 1.35v memory available, to run at or above 2133Mhz cheers.gif .
