Elpidia Hypers on FX-8120

[BeepBeep2]

Nice results Dave ;D

[FlanK3r]

Oh Dave, I like your FX results as my old Thuban 1090T results :-D. Nice! 7-7-7 is awesome in blend test. What is DRAM voltage in bos?

[mav2000]

Nice, which Elpida kit is that. have a whole lot of ram to test soon. Am waiting for my FX to arrive.

[Daveburt714]

FlanK3r: Mem v's are @ 1.70 in bios. I tried it @ 1.6875 but it would fail ~20 minutes in...

mav2000: It's an older Corsair GT kit (2x2) 2000 CL8. The part number is in the SS on the CPU-Z spd tab.

[FlanK3r]

Dave: what about this little challenge? http://www.xtremesystems.org/forums/...=1#post5058871

[Oliverda]

I hate to Necro an old thread, but I think I was wrong when saying that Hypers didn't play well with FX chips...

After ALOT of testing, it seems my problems were related to using the 1866 divider.
Switching to 1600 and using the HTRef clock gave me much better results!
Guess I should have paid more attention to what some of you folks were posting.

I'm pretty happy with them now that I've been working with'em for awhile!
It's only 40 minutes, but Blend pushes things WAY harder than everyday use, so it's probably good...
Time will tell.

Guess I'll stick with this kit for awhile.

Nice. Can you provide more detail on the rig?

[BeepBeep2]

Are you sure it was related to the divider Dave?

Hi Oliverda, haven't seen you around in awhile...

I updated my sig, so all the info is current. It's an older 4GB (2x2 kit/part# is in SS), I doubt it's even available anymore and it was pretty expensive when I bought it!

These clocks have been really stable though... I even used RipBot to encode a movie with it the other night (my most stressful real world use) and it did just fine..

The biggest problem with these settings is I can't find a good balance between all parts (Cores/IMC/Mem).
The cores are good up to ~4.75 and the IMC is good up to ~2.55. I still need to work on the balance a little, I hate losing core speed...

I'm going to play with the 1333 divider tonight, but I get the feeling HTRef will become a limiting factor.
At stock board v's (NB/SB/HT) it gets a little flakey ~270 HTRef.

OFC, I can't help myself man... Pretty sure theres a little more to be had and keep stability.

Nice to see you around again Bud!

I can't say 100% Beep, my mem skills aren't really that good...
Switching to the 1600 divider opened them up for me though.
I had a hard time getting them stable above 2000 even @ 8-8-8 with the 1866 divider though.

[BeepBeep2]

I'm sandbagging a little...on the 1866 divider which is why I asked. I wonder if it does have to do with subtimings or individual CPU.

Of course, this isn't Prime95 Blend or anything but you can usually expect ~60 MHz less in blend.

AMD FX-8150 2 cores @ 5.26 GHz, 2.52 CPUNB 1.524/1.23v

watter is plus for FX....I can go higher with CPU clock and air , my limit is 5170 MHz for 32M

With 8 cores enabled, right?...I had 2 for a reason.
32M is only 12.5% load. It doesn't matter whether you have air or water, unless you are running on the stock cooler or something. In fact, it's possible for air to have lower idle temps than water...

Unfortunately my current MSI 990FX-GD80 doesn't really like them but few months ago I had an opportunity to test them in a CH V.
I was able to OC that four modules to 2133 MHz. What I've seen Crosshair V Formula is far the best memory OCer AM3+ mobo.

Thats the same stuff Oliver...

Just so you know, the Sabertooth clocks pretty darn good too (including mem) if you need to save a few $$$.
The bells and whistles of the C5F are nice though, I especially like the I/O panel CMOS reset and ROG Connect.
The price difference here has stabilized and the C5F is only ~$40 more than the Sabertooth (and probably worth it IMHO).
Just wanted to let you know the Saber is a nice board if you need to save some cash.

Also, if your going to use those GT's don't be affraid to try the other mem dividers!
I'd like to see your results...

L8r..... Dave

He said he was able to get 2133 with those sticks on CH V Dave

Point taken...

I really didn't see any advantage to mem clocking on the C5F over the Sabertooth, but then again, my mem skills are admittedly weak.

I think if you get 2000 C7 for 24/7 out of those sticks then you aren't that bad...they aren't very strong sticks (since Corsair binned tight) as far as Hypers go. It might be an issue of your IMC more than anything when it comes to CL8 not scaling further. (though I question a little with both 8120/8150 CPUs! )

I tried up to ~1.8v real vdimm on my sticks to push 2180 7-7-7 on the 3:14 divider but they won't go... might be my IMC or CPUNB frequency. They seemed happiest benching 32M at 2133 7-7-6 1.75v. I'll be stuck around 2050 for 24/7 use.

sub timmings pics for stability at 2133mhz 8-8-8, can u provide it?

[BeepBeep2]

I can certainly guess, but the key here is drive strengths.

I run a different CPU now since then, this one won't do 2133+ stable (but I'm still working on it) and I don't remember exactly what subtimings I was using with the old CPU.

[bynext]

I could't get 2200 7-7-7 even with 1.85v.




but is stable with 1.45v on cpu/nb

[BeepBeep2]

That is too much voltage for the CPU-NB...
Also, not many sticks at all can run 2200 7-7-7...your ram is not up to the task. If you bought higher binned ram like GTX2, got lucky with IMC and used 1.8v DRAM you could do it.

Also, I wanted to mention that 1.85v with Elpida Hyper isn't really safe in long term either...and 32M isn't a very good stability test.

too much even using just in benchmark ?
for 24/7 what is the max safe voltage for cpu/nb ???
if i put 2800mhz on cpu/nb i can't boot even with 2000mhz 8-8-8, i think my imc is not strong. don't hang 2200mhz with tigh timming and nb at 2800mhz.
i will get some ripjaws z 2400mhz and try a little bit more with this cpu..

Then don't put 2800 MHz on CPU-NB? Most people here run 2400-2500 MHz...
Also, subtimings and drive strengths play a big part on FX. I can run 2100 7-7-6-19-26-90ns 1T stable with ~2600 MHz CPU-NB and that is REALLY good for 24/7 use, even benchmarking...but I can't even boot 6-6-6-18 @ 1600.

I think doing 2600+ MHz on BD for 24/7 use is like running 3 GHz on Phenom II.

I use up 1.2875v set to run Prime95 at 2618 MHz. I wouldn't set more than 1.3v to be honest, this board already overvolts a lot assuming you have LLC set to "High" for CPUNB and setting 1.45v will be giving your CPU near 1.5v CPUNB...

I would stay under 1.4v under all times even when benching. "Zeus" here degraded his CPUNB by leaving the bios on AUTO by accident, it set 1.4v and he after needed more voltage to reach the same clock speeds.

For example:
This is what I set:
CPU Voltage 1.44375v LLC Ultra High
CPU/NB Voltage 1.28750v LLC Regular
DRAM Voltage 1.71250v

This is what CPU-Z/AI Suite II Software says is real:
CPU Voltage 1.440v or 1.452v
CPU/NB Voltage 1.330 or 1.336v
DRAM Voltage 1.726 or 1.733v

My Digital Multimeter reads:
CPU Voltage 1.454v
CPU/NB Voltage 1.338v
DRAM Voltage 1.739v

look, my drive strengths settings and others..





thanks , i'll use a Multimeter to read that voltages...

[BeepBeep2]

Try this for timings:
DRAM CAS Latency - #
DRAM RAS to CAS Delay - #
DRAM RAS PRE Time - #
DRAM RAS ACT Time - #
DRAM READ to PRE Time - 4
DRAM RAS to RAS Delay - 4
DRAM WRITE to READ Delay - 4
DRAM CAS Write Latency - 8
DRAM WRITE Recovery Time - Hypers should be okay at 10.
DRAM Ref Cycle Time - Try 90ns, if that doesn't work, the next time try 110ns, and after that 160ns. Some Hyper might need all the way to 160ns to work. Mine work at 90ns (faster).
DRAM Row Cycle Time - Make this one tRCD + tRAS, meaning "DRAM RAS to CAS Delay + DRAM RAS ACT Time"
DRAM READ To WRITE Delay - 6
DRAM WRITE To READ Delay - 3
DRAM WRITE To WRITE Timing - 4
DRAM READ To READ Timing - 4

For DIGI+ VRM:
CPU Load Line Calibration - Ultra High
CPU/NB Load Line Calibration - Regular - Please note that you will have to give up on pushing CPUNB to 2800 and you will need more voltage for XXXX clock than before.
CPU Voltage Over-Current Protection - Disabled
CPU/NB Voltage Over-Current Protection - 130%
CPU PWM Phase Control - Extreme
VRM Over Temperature Protection - Enabled
CPU Voltage Frequency - 420KHz
