Not All 8rda+'s are created equal

[Justintoxicated]

well after a long wait i finaly recieved my new 8rda+...Poped the sucker in and I final see why you all say this is a great board.

I went right to 10x200 FSB and i have since been looping prime 95 for over 12 hours...Next i get to see how high this sucker will go, but im finaly satisfied at 200 FSB since im oonly using PC3200 C2 (ill bet i can get a bit higher though :) ) ...

Im using the default bios, and im wondering if people are still seeing a large loss in preformance with a multiplier less than 10?

Im not sure how much higher I will be able to get my 1800+ to on air without lowering the multiplier. but everythig should be topping out soon (MB, Memory CPU)..Its temperature under load with FRESH as3 is about 46C. at 1.85V (probably only 1.825 or less needed at this speed)

Not bad at all for a budget air-cooled system...I still have to run benchmarks but im sure they will be sweet also.

My old 8rda+ was a rev 1.0 my new one is a rev 1.1
my old one maxed out at 190 FSB, my new one booted right up at 200x10, and i have not even maxed it out yet!

P.S. my onboard lan really was DOA on my old board also, the onboard lan on the new board works compleatly perfectly!

[N8]

Glad to hear of your sucess! :)

[nikhsub1]

Did you note the VDD voltage on both boards? Most likely the new one has higher VDD than the old one...

[Justintoxicated]

ahh yes, the VDD! I did notice something there that puzzles me!

they are both exactly the same! And it is sorta low IMO..

Both boards gave me a VDD that fluctuates between 1.56 and 1.58...both boards have the SAME VDD (rev 1.0 and 1.1)

The only difference i noticed betweent he rev 1.1 and 1.0 is that my GF4 4600 is slight (and its not much difference) farther away fromt eh DIMM's..And of coarse my Lan works now.

I know i know! EPOX says the REV1.1 did not fix the GF4 killing problem, but on the 1.0 board my GF4 4600 actually rested against the DIMM on my new board there is a mm or 2 space in between, and the card actualy installs fine now without having to flex it. Did epox lie aboutthe revision? Well im not so sure, perhaps this varies from board to board also, but there is a definate difference in clearance, even if it is not much!

[Qkjhfhaiguihfma]

Just out of curiousity, when my board gets here, will I have to do the VDD mod to get anything out of it?

I hope at least 200Mhz dual channel is achievable without the mod?

[Justintoxicated]

i have not modded mine yet, but i dont have a second stick of Ram yet either. I think you should be able to though.

[muzz]

We sure are glad this one works right Justin.............;) :D

:toast:

[Justintoxicated]

heh i bet, your probably all tired of my ranting by now...

Thanks for everyones help and support, ill report more once i find my max stable CPU/FSB speeds... Prime is still looping at 200x10 though so im happy :toast:

[WannaGoFast]

I just put together a new 8rda system for a freind, and also noted that
there was plenty clearance between 4600 and dim slot as well.

Just a play on the thread title...I've hosed 2 8RDA...I'm on my second rma as of 2day...which means I'm on my third board now...in 8 daze...as far as I can tell...I toasted the bios chip both times...I could power uP the board without the fan or memory...but that was all I could do...I was able to run the chip uP to 2500+ (11.5*221) on all 3 boards with the memory benches at over 3400(3*2*2*2)...I have no clue as to why the boards roasted...I'm sure the people at Mwave don't wanna see me again anytime soon...the real pisser is the 120mi round trip drive...phew...that's 360 miles!

[Justintoxicated]

id ratehr drive 2 hours than have to wait for over 3 weeks like i did, well ok maybe not heh..

Make sure your MB is not grounding out on anything, i had a Mb before that had random problems because i had extra posts behind the Mb (i wasent paying enoug attention when i installed it or i was too tired). I hope you have better luck with your next MB.

Know what though? i just fried the bios on a 233 MB, trouble is the thing is too old to fix (AMD 233 lol). Everything powers up like you said, but there is nothing on the screen. Never messed up a bios before, but if it sounds liek what just happened to my other MB.

[SupaMan]

my 8RDA+ will be waiting on my doorstep tommorow. I cant wait to see how well it does...

[Justintoxicated]

Ok im happy, lets see if i can be any happier :) Then we will see again when I V-mod..BTW i ran Battlefield 1942 While running prime at the same time, it ran with no problems.

What are you using for the VDD? in USDM I get a constant 1.6 but cant oc past 196fsb sync?

[muzz]

Brad I don't think it has alot to do with what the vdd is... I had 1.56 b4 the mod, and was able to do over 220 NP.......I now run 1.77 ( as it was already doing well) and it is a little more stable over 230.

Seems to me some boards need a little more vdd than others, as others had the same or more vdd then me, and they still couldn't go that high b4 doing the mod.

Good Luck

I got a message from OCZ to supply my details for RMA of my ram which I did and heavent heard anything back? I supose its only been a few days since :confused:

[baller02]

vdd works;)

[Justintoxicated]

Well i guess my new board is nothing spectacular.

I cant get past 200 FSB and have a stable system.

Anything over 200 and i get BSOD's Not even 202 FSB

I dont think it is the memory even though its PC3200 C2, Adding voltage does nto allow me to get to 202 FSB, not even if i lower the multiplier to 9. It can't be the CPU...

It does the same thing as my other board only not untill after 200 FSB... Perhaps i need to update the bios, im still using the stock one.

[SupaMan]

i got my 8RDA+ today, v1.1

I cannot use it yet, i just ordered the remainder of the system. I better get a good FSB, i bought a Chipset waterblock :D

i'll fill u in once its up

Does anyone know of any software that will allow the setting of the fsb speed on the fly...and if so...what pll do these things use...

u killed 2!!!??? wtf do u do to them?

i only killed oen mobo ever, it was an A7V that my retarded self ( i was pretty new then) flashed with a winflasher....00ps!

[sysfailur]

Stepper, you would be talking about setfsb. Currently an nforce2 version is not made. But I have word from the Author that he's working on it.

[Stepper]

TY...perhaps I can beta test it...as U can tell...I'm pretty good at blowin uP things...ahh...I mean stress testin...

[Tweaked!]

Hey Sysfailur, what about the Msi K7D??? Expect a version for that? Sorry for the off topic btw:rolleyes::cool:

[N8]

Wonder if the 8K7A 1 will work on the K7D :)

200 FSB is the limit of this board without V-mod...

How much performance increase would i see running 2 sticks of ram Vs 1?

Sandra is reporting about 3000 points in buffered, As is.

Also if i order a second stick should i get another stick of Corsair PC3200 C2, or should i go ahead and get the PC3500?

[Crazymofo]

sell the stick of 3200 and get two 3500

Justintoxicated...what do U mean by...200 FSB is the limit of this board without V-mod...the corsair pc3200 is a bytch to set timings on...but to say that the limit of the board is 200 is nuts!...what are Ur settings for Ur memory...multiplier...voltage...yada yada yada...email or pm me...that board flys!!!...take a look at the screenshots that I've posted in this thread...

[Justintoxicated]

No really 200 FSB is the limit. My last 8rda+ would only do 190 FSB before i ran into the exact same problems this one runs into at 200 FSB.

Its Corsair PC3200 C2 and i Can't run even 202 FSB with timings at 6-3-3-2.5 and 2.9V to the ram. but its perfect stable running 5-3-3-2 at default voltage. This board is limited to 200 FSB, plain and simple! Its better than my first 8rda+ that would only pull 190 FSB. you have a different board, and like the topic says, not all 8rda+'s are created equal ....

200 FSb isnt that bad though i dont think, is that less than normal for the 8rda+?

NOTE: I havent tried ny different Bioses yet, this could also be the problem.

And do the multiplier below 10 still reduce performance on this MB?

CPU 1800+ @ 2000 MHZ 1.825V
Memory Default Speed, timings set to 5-3-3-2 instead of recomended 6-3-3-2

200x10, memory at 100 % CPu turned to agressive mode.

What problems are U having...have U tried to pump uP the voltage...do U have the cpu & memory set to expert & aggressive...IMHO...there are way too many settings for you to say that 200 fsb is the limit...others that have posted here are running timings higher as well...I'm not a huge fan of the memory myself...but I've got numbers that asy otherwise...(3*2*2*2)...I'm in no way tryin to argue with U...I'd just like to see U get the results that U'd like to get...at any rate...'Keep Trying'...

[Stepper]

...jus a thought here...have U tried removing the jumper on the FSB Frequency posts?

makes it clock more stably

Apparently!

[PiLsY]

Mine was pretty much the same. 206mhz if I used the 6x multiplier and default cpu multiplier, 196 - 198mhz depending how it felt if I was topping out the cpu. VDD mod got me up in the 225mhz range though. 6x and default volts now gets me 225mhz stable @ 2/5/2/2. 226mhz wont get into windows. 9.5x gets me about 222mhz or so. Still not found the stable limit here. 10 x 220 is stable, but seeing as this is a server I dont feel happy ramming it with 2.0v. Temps are above 50c at that speed and volts. using 1.8v @ 9.5 x 220+ is a lot better. About 44c under full load.

PiLsY.

[SupaMan]

interesting, the manual says it changes the FSB to 133 or something like that...

[WannaGoFast]

Got mine to.....installed it...killed dead in less then an hour.

corrupt bios chip it seems

going to pickup another to try here in a bit.

hope its better

Bummer man but that is exact the reason I buy all my motherboards locally and pay the extra $10-$20 for it. I hate waiting for §§§§ to be RMA'D through the mail.

Me to bro, and mine was 20 dollars cheaper then most....got new board in and its all good now :)

TCWO.Com has a great price on these boards

see if this one does a lil better

[Justintoxicated]

Yea i tried different bios settings, CPU is set to agressive. im about 36-38C idle and 46C peak under full load. I can't get past 200 FSb without a Volt mod. This si the second board i have tried.

Im using an enermax 550 Watt 650 watt peak PSU, but my VDD is a bit low, the same on both boards though. The limit of my first board was 190 FSB this second board i cant get past 200 FSB no matter what voltages, multiplier i use ect.

Guess you all have better luck than i do in hitting those high FSB's and retaining stability. Im pretty sure its jsut that we can't expect all epox 8rda+'s to overclock well.

Oh and yea i removed th jumper.

Does anyone think its jsut because Im using the stock BIOS? I havent tried any other yet in fear of gettign worse results, or hosing something before school starts.

[Stepper]

What problems are U having???

[TechTones]

There is ONLY 2 ways to get up there provided you have ram that can do it.

1] extreme cooling on the NB. I have mine water cooled

2] The vdd mod. Mine is at 1.87v


These are very relaxed timings 7-3-3-2.5

[Stepper]

I'm not gonna say a word...@#$##$&^&*:censored:...see...

[muzz]

Justin..... you've been around mang..... and you know what you have to do if you want to ( BTW RUN OUT OF the SPEC of THE BOARD) go higher......:D

You didn't get lucky...., but still do ok.
You don't want to do it, thats fine np here...... but I think you know the deal.... you just have to figure out if it is worth it to ya to do it.

Good Luck ( I knew your happiness wouldn't last........;) )

[WinXP]

I agree with Justintoxicated about the 8RDA+ not being equal. I should have never rma'ed my first 8RDA+. When I recieved it new one corner of the bios socket was broke off an in the bag when I removed it but I wanted to try it anyway an without vdd 210fsb but a little unstable with 2 sticks of mem in it. After vdd set to 1.8 227fsb with out a problem. But was concerned about may later on have a problem with bios chip. Recieved new 8RDA+ an all I did was remove the previous mobo from case. Installed same cooler to northbridge,southbridge, an power chip. Installed same cpu,mem,video card an HPT raid card. Booted right up no problem. Lowered multiplier to 8 raising fsb to see were it peaked at same timing as used before (exp,agr,100%,62,2,2,2), toped out 185fsb at 2.77v, first mobo at 2.77 reached 208fsb. Set mem to 2.9v reached 190fsb an that was it. Tried vdd now to 1.8 now 195fsb an would not go any higher. At 190fsb the nic crapped out an sound stopped. First mobo when set to 2.63v to mem mbm showed 2.63v second mobo 2.56v in mbm, at 2.9v with first mobo showed 2.9v in mbm an in bios. Second mobo at 2.9v mbm 2.81v an in bios. Waiting on another one to arrive that one had to go. They all are not created equal an on the second mobo lowering mem timing to exp,opt,100%,8,4,4,2.5 made on difference even with 1 stick of mem.

[muzz]

This has been the way it's been since the start, no 2 boards ( or any piece of electronic gear)are created equal......
From any manufacturer.

[WinXP]

You are correct there are no two equal. But there is not this much of a difference in a group of mobo or whatever it may be unless there is poor quality control. I have had 3-8k7a's, 6-8kha+ an 3-8k3a+ an non of these were identical but they all ran with in 10mhz fsb from each other. Before switching to Epox I run Abits an they all ran close. Why would anyone buy a mobo if it was not better than what they had an the first 8RDA+ was a very good board just a little better than my 8K3A+ i use but the second one was garbage in my opinion.

[muzz]

Fair enough.

[BMORIN]

Muzz, did you put any special cooling on your NB when you upped the vdd to 1.77?

[muzz]

I changed the crappy HS (that sucker used to get screaming hot- thing don't even have a fan).. and installed a 40mm low profile hs with a 7.4k rpm fan attched..... runs cool now. SB got a passive 40mm. Barely gets warm.

[Stepper]

Yes it can be done...no it won't run Sandra...however...

1. It boots into winblows and does work ( I took this screenie didn't I )**
2. It's on air...no mods...3*2*2*2 memory timingz with 1 stic
3. Yes..U can do it too ( Bios Roastin voltage...proceed at Ur own risk! )***
4. Who's Ur Daddy!!!:eek:

**I usually don't use Frank-In-Stein to surf...but I'm on him now...posting this!!!:cool:

***RTFM!

[Espen]

Ill get my second 8rda+ tomorrow, my first one did only 180fsb sync without any mods. With the VDD mod+ better cooling on the NB I could run it at 203fsb in sync with 2x TwinMos 256mb ddr400 sticks. Hope I have better luck with the next one...
My first 8rda+ died sadly:(

[Espen]

Just got my new 8rda+ and its rev 1.1
Right now im running at 225 fsb in sync with stock heatsink and VDD mod.
Will add a larger heatsink to the NB tomorrow and se if i can go any higer.

[Shuki]

justintoxicated... sometimes its the little simple things that slip by so I ask, "have you tried moving your stick to a different dimm slot?"
