msi 790 fx-gd70 thread

[Tony]

The FASTEST way of running these CPU's is 1333 mode and clock up HTT and ram with tight timings....who cares about 1800? i don't

[massman]

Its not OCZ.....

ES chips

Ask them to do it on retail chips with publicly available bios's.

We pulled 1800+ on samsung IC's with an ES chip. I could never tune the sticks in @ 1800 when I swappped to public bios and 955.....best i've done is 856 on retail so far...so 1700+ can be done.....

I think part of it has to due with the ES chips not having 100% bios support, on the same token I noticed ram performance is a tad sloppy with them compared to retail.....I can't clock ram higher but get better results lower on retails.........

I still have my ES chip if you would like a comparision but I already confirmed it.

I was actually hoping for this answer, so thanks .

1700MHz shouldn't be a real issue on the GD70, but may be on other boards. I tested the DFI DK and I couldn't even get the board to work at 1700 1M stable, whereas the GD70 allowed me to do even higher (for reference: http://www.madshrimps.be/?action=get...61&articID=926, sorry for url, but hotlinking pictures doesn't work).

During the tests, I noted down that this issue may have been related to the overclocking itself, so increase of HTT. Could someone test for me if the memory goes equally high using the 1:4 and 1:3.33/1:2.66 divider? I would do the tests myself, but haven't got an AM3 setup put together at the moment.

Easier to get 1600 with 240 fsb 1333 divider if thats what your asking.....performance seems a tad faster to......runs a tad hotter as well.....

Haven't tested 1700+ on MSI yet.....gigabytes already done it though in my review with the 955. Last 2 3d 06 bench shots...

Try increasing NB volts ( 1.28-1.30 ) when attempting high ram clocks ( actual NB not cpu NB ) It may or may not help, might be board dependant....helps on the gigabyte.

Should be a safe range...I'm sure you well know that 790GX defaults at 1.30 NB volts...

Hey all,

790FX-GD70 has some secrets and I would like to share them with you:
1. CPU Temp and Digital LED
The MSI 790FX-GD70 has a 2 digit debug LED on the PCB. When you upgrade to BIOS 1.35 beta (later 1.3 final) it can also display the temperature.
In fact, we can also show system temp or other part…But I think CPU Temp is most popular for OCer.


2. Measure Point of Voltage “lite version of OV Kit” (Check Red Point)
NB PCIE Voltage
Memory Voltage
NB HT Voltage (Near DRAM, under Heatpipe)

NB Core Voltage
SB Core Voltage(Near SB chip but cover by Heatsink)

CPU Voltage
CPU NB Voltage(Near Debug LED)


Hopefully you will like them

P.S. Sorry for the bad pictures, trying to resize them.

Any chance of showing us a vdroop mod marco for ln2 benchers?

I don't need warranty

[jonspd]

chew* tried your settings and they didn't work for me...


it has more secrets then that no one is letting them out yet tho

really having a hard time with mine TBO 2 days and not looking to good IMO.

I know there is alot of settings but which ones are the best and which ones have the best reason to be messed with. I mean come on how many of you guy's have played with all the voltages already on this board in different combos? At 3.7 but any higher has problems with a 1600 ram note the 1333 ratio.

[chew*]

Did you prime stable at 1600 ram speeds for 3 hours or more before introducing any other part of the OC?......voltages needed are going to vary depending on cpu....I can toss another 955 is and I'm willing to bet those voltages do not work.......not to mention what ram are you using....and is it truly 100% stable.

I've had board less than a week...still exploring, can't complain since it benches 4 gig as all the other boards i've tested. Nb isn't quite up to speed but......I was using my crappy xigamatek....My True handles the heat load of NB clocks alot better.....

I've played with quite a bit of settings ( been on board for a solid 80 hours so far ) I just tried to K.I.S.S. for you guys.

Prime stable setting I put a solid 24 hours into....and note this comes rather easy to me......you might have to take a tad longer...

Not really.

While doing the overclocking tests for the review, I was wondering if the 850MHz barrier was due to the combination of HTT and divider or a design flaw. If it's a design flaw, you'll be able to max out the memory frequency on any of the 4 dividers if the HTT allows you to go that high. If it's a combination of HTT and divider, it's possible that a different divider will allow you to go higher.

Forgot to test it

[chew*]

Gains are minimal when using 1333 divider.....I don't think its a design flaw, I think the cpu likes the lower divider and HTT increase better. Noted on 2 boards thus far.

[TiTON]

Macro-MSI - thank you for sharing the read points.. i did notice the cpu and cpunb by the LED.. but had no idea there were more read points under the heat pipe

Yea kinda like the nforce days where the 10.5 or less wasn't as good. Agree

I was thinking this also there is alot of combination's that can be done. and the true gold for all of use is which ever gives the best performance.



Chew no I only used in-place for 24 and then another 12 at 2 different settings. Pretty sure these gskill are 2x1gb d9's have another set as well so don't think it's memory cpu maybe but just don't fell like it. Wide range on v's doesn't help or hurt cpu speed at 3700 with 1.4625 for 2 day then 1.43 now in bios.

[chew*]

I run blend religiously with AMD, the IMC makes it almost a requirement......1024K is the first test and will spit out an error quickly if the IMC or memory is pissed, it will toss an error on 640k/512k/448k around 2-3 hours if your almost stable.

This saves alot of time....

If your failing on 8k/10k/12k/20k etc etc.....its either heat or cpu voltage related.....if voltage you will usually just crash. If it errors its usually heat..

Studying each bench and Knowing why it fails makes diagnosis alot easier....this is why I stress test each part of the OC individually.

Because I know why a bench fails at a particular point I can toss everthing together in one shot now.......You need to learn why it's failing though thus the 3 step approach, you will get a better understading and grasp on it this way.

[DaMulta]

Almost had 1800

Seems like the voltages that needed to be played with.

CPU-V
CPU-NB
DDR-V
NB-V

[chew*]

try PI 32m..........No offense but I can bench everest with 1000 errors in memtest, Rather you not give users the wrong impression.

[DaMulta]

I'll give it ago, still jacking around on the stock cooler.......also don't have my note pad in front of me like an idiot.....

LOL Notepad is a must

[demonkevy666]

the 800mhz divider probably works the best.

but then how are you going to get a board that go past 400HHT ? .......just for 1600mhz ddr3.

[DaMulta]

Ok this is nuts

fsb 220
Multi 14.5x
CPU-V 1.46v
CPU-NB-1.170
PLL-3.522
DRAM-1.90
NB 1.60
HTLink 1.230
SB-1.280

Runs 1 over and over

Now I was starting to get 2m by upping the CPU-v BUT like I said stock cooler and the voltage cought up with me.....

[chew*]

Yah 1m is easy, just a tad harder than everest.

thaks for the read points but it'll be a pita to probe when populated maybe ill solder some very thin wires with butt conectors labeled

[DaMulta]

Yah 1m is easy, just a tad harder than everest.

IDK but I have never really ran Super Pi for some very odd off reasons

LOTS OF RESETS(it would not start/memtest would not start) to get just that. LOL Today 06:14 AM to 10:44 AM just trying to hit 1800 and getting what was close to it simi to stable.

Crazy how hard it gets from 1700 to 1780.....

Trust me run 32M PI..........or all that work will get you is the ability to run 1M pi and everest........No other benches will pass.

What OS are you running? Yes, it makes a huge difference.

[shadow_419]

I tried my hardest to get 1600 on these g.skill 1333's but they won't pass memtest so forget about prime blend. I'm running prime right now with my x3 720 @ 3.4ghz (200x17) 1.3625v bios 1.358v cpu-z 1.352 load cpu-z. I can't dmm cause I'm out of batteries lol. Once I finish 4 hours of prime (one more to go), I gonna go back and see if I can squeeze anything more out of the ram.

Yah I keep forgetting that woops......xp 32bit SP3 for those settings guys......and obviously 13b6 bios....
