Hey guys and girls,

I could not come up with any answers this weekend to this problem and was hoping some of the folks on this board can help out. My computers main use is a home theatre pc. On the weekend, I got a great deal on two 5.1 surround systems (spherex xbox 5.1 system). The inputs can either be optical or digital coax for full surround.

Here is my problem, I am using the optical s/pdif out for the setup in my living room where one of the 5.1 systems is and it's working great. My other 5.1 system is for the computer/gaming room. Is there anyway to hook up the 2nd 5.1 system in my computer room? I am thinking I need some type of analog (from the ip35's 7.1 outputs) to s/pdif dongle/splitter/adaptor or something?? Any ideas? Here is a picture of what I have to work with on the sound system.

The IP35-Pro has optical in and out. Why can't you use that just like your other setup?

Just wanted to give my thanks for many of the posts on this thread. Made a huge impact on my decision to go with this board, and everything has been running smooth!

This program is pretty cool... reports my E8400 at 4GHz as 35c, which I think is more accurate than 45c considering the ZeroTherm NV120 I have on it. The XSBench is also pretty nifty Would be neat if there was also a "submit" button to upload it to a server for comparisons

i hope unclewebb comes up with a 64 bit version...i transitioned over to vista64 about a month ago...i do have dual boot with XP SP2 as my back-up OS.

same computer, 2 seperate 5.1 systems in 2 different rooms

I thought it would be easy too. His deal is different than mine, I attempted to run my PS3 to the digital IN, but I'm guessing I needed a decoder because I mostly got bleeps and blops for the games.

[Ace-a-Rue]

no beta update this week as long as CeBit is going on...i was told by Bingo13 that the bios engineers go to CeBIT to answer those pesky performance questions on the newest chipsets

Yes, you need a Dolby Decoder. Not sure if the Realtech has that as I use an X-Fi, which does. That is how I run my Xbox 360. Real easy in XP but takes a bit of work in Vista.

Well, there is such a thing as an optical splitter. It looks like this : http://www.cablestogo.com/product.as...=102&sku=27027. But 2 rooms worth of toslink cable might get a bit expensive.

compared to my previous post and after doing the WinXP Tweaks...
am I finally doing this right:

[Cpl Ledanek]

I dunno...this is kinda scary now...any advice or hints what I should do...first time I OC a cpu

[BenSanford]

Well, I finally got my board to work with all Four 2GB sticks! It would work fine with either pair for a total of 4GB memory, but wouldn't even boot with them all installed. I had tried just raising voltages and relaxing timing, but no dice. Then after a suggestion on looking at timings in MemSet and further tweaking I finally got it working. I tightened many of the memory timings, and relaxed tFRC. The timings I currently have (from MemSet) are as follows, which can be compared to the earlier timings (which were the "AUTO" settings in BIOS) which are also listed. I intentionally tightened the first few timings to the specified timings for my memory, and intentionally lengthened tRFC since a poster suggested that it might be one of the ones to play with.

I also raised MCH to 1.33 volts and ICH to 1.09 volts. (I had previously tried just the voltage increases and they alone were not enough to get all the sticks to work, so I suspect it was the timing changes.) Timings were set in BIOS and read out via MemSet.

Of course, Vista wasn't happy and insisted that it be reactivated, which necessitated a phone call to Microsoft. The "nice" lady there seemed to want to imply ("how many pc's is your software running on?") that I wan't legal, but gave me the new key that I needed.

Readings from MemSet: the 1st timing listed is what is now working. 2nd timing listed is what didn't work with 8GB, but worked fine with just 2 sticks.

I think I'm going to settle with 498x8 as that seems to be providing me with the best performance/stability island - details in the pic:

have you tried slightly lower vcore to run orthos?...if so, what vcore?

GOOD SHOW!...you were persistent and it paid off big time!

as to having to get a new key from M$, they have a scoring system which is part of your install...the scoring system is tallied and stored as a digital signature...from there on, it keeps tabs on changes to your system hardware...if you change the original point tally by 3 points (total points are 10), then you need to get a new key...thing to keep in mind, the network card is worth 3 points where as hard drive and memory is worth one point...what i am not sure; adding and subtracting multiple hard drives and multiple memory sticks count as only one point, two points or more....probably, your swapping out memory sticks set the M$ monitoring bell off (big brother keeping track) forcing you to call in. most likely

this is how M$ keeps track of mobo changes...possibly, as their thinking goes, you are trying to install the OS on a secondary computer, which is not allowed....that is what they are trying to prevent.

[Cpl Ledanek]

have you tried slightly lower vcore to run orthos?...if so, what vcore?

I thought I set the Core Voltage at 1.3 in the BIOS but, it seems to be read by CPUZ @ 1.28, don't know if that's the same one we're discussing.

Remember, I never OC any PC before so this Abit IP35 is taking my virginity away

BTW, where can I get these 40mm fan? and how do I secure them on the board once I install the board inside the case?

As, always thanks to everyone for sharing their settings and experience.
I'm learning so much.

Thanks for the input. The s/pdif splitter is closer to what I am after. The problem I have with that is that the sound will be the same on both speaker sets. I would like the ability to have media center running in the living room on it's own sound, and me playing a game on the other 5.1 system (from one computer still).

The optical and analog ports will both produce sound from the motherboard audio. Since my living room setup has taken the only s/pdif output from the onboard sound, I am left with the 7.1 analog still. Is there not an adapter of some sort (can't find for the life of me) that will take the analog output from the htpc and convert it to coax or optical digital for me??? Looking forward to some more feedback here!

Toslink cost not an issue with ebay. I have 50 foot dvi's hdmi's and toslink now added to the mix for cheap cheap cheap on ebay!

[Cpl Ledanek]

I lowered the Core Voltage to 1.25 I believe...see if you can make a recommendation:


advance thanks

My guess is your going to need another sound card to play 2 different things from the same computer.

with the E8400, it is about the same as my QX9650...to get a 1000 mhz over stock, i've seen about 1.28-1.30v actual vcore...remember, this is not locked into concrete since every cpu is different when it comes to overclocking...

this below overclock (your image) is using to much vcore, in my opinion...try lower vcore for 3.4 mhz

yeah I think that's when I was using the uGuru to "play with"...but now I'm doing everything in the BIOS....I'll go back to 1.30v again, let it run for 8hrs and see anything would pop up.

Then I'll probably bring up the Bus Speed...just don't know what's the next number I need to enter...what's next to 334.0 MHz?
Is there a website that tells the next scale number?
That part I didn't find a link to how to scale....
I'm just trying out one parameter at a time.
Advance thanks...

Found this on [H]ardforum:

note: i'm a n00b

E8400 FSB = 1333/4= 333Mhz
E8400 Multi = 9

E8400 Speed = FSB X Multi
___________ = 333 X 9
___________ = 3000MHz (stock speed)

to hit 3600Mhz CPU speed:
3600/9 = 400Mhz FSB

to hit 4500Mhz CPU Speed:
4500/9 = 500Mhz FSB

maybe I'll got 400MHz...if that 333MHzX9 runs stable for even 4hrs.

[Ace-a-Rue]

stay 1:1 FSB to memory while you adjust the other parameters.

MCH, ICHIO and Vdimm play roles in attaining max overclock besides vcore.

try MCH of 1.4x; ICHIO of 1.65 and Vdimm of 2.1 to 2.2 to attain 3.6 mhz using 9 x 400 FSB (CPU VTT set to 1.3)....you can adjust up or down from there to see if it helps or hinders.

use Uguru to adjust your voltages...cpuz vcore is fairly accurate for vcore readout...don't forget that cpuz conflicts with uguru when both are visible on the desktop...just minimize Uguru when you want to open cpuz.

once you got your final overclock then adjust your FSB to memory ratio to see how high you can get your memory...don't forget max memory speed means more stress so voltage increases might be necessary to hold it stable.

good luck!

[Cpl Ledanek]

can't wait to go home

[Tsuchiro]

just changed my hsf to TRUE from zalman 9500..... my cpu temp went down but my pwm went up... think my 9500 was blowing on to the hs for the pwm... what size fan should i get to mount on to my pwm and how? with zip ties?

I didn't find that in the BIOS or uGuru
When I did enter those settings that I can find, after I F10 and rebooted, I got a C1 reading on the POST code displayer
