Areca 1880

[Computurd]

no read ahead on top, read ahead on bottom. hate to see the ten drive array get embarrassed by those x-25e's though. wonder if i have to many devices on, strangling the ROC? your random is much better. the latency spikes are less pronounced with the 4g. i take it you are still on 1gb right?

[Anvil]

Still 1GB cache, I'll do a quick test using no read ahead...

wow much better seems read ahead is introducing the big spikes... i know it has a negative impact on latency of course..

Great score using 2 small drives

im tellin ya...its a racehorse! i am on the edge of my seat for the SF drives on there!

[safan80]

anybody have any actual file transfer info?

[Anvil]

Same test using VOL read ahead

I'll play with this setup until tomorrow...

edit:

It's getting better

OC 4GHz, pcie 105 (two consecutive runs)

new firmware +FP @ winsat
128k stripe size No read ahead and WT

[Anvil]

Tilt,
I should have kept the new firmware for a day or so , but the initial tests were terrible! (don't know why, just plain awful)

wow much better than mine! hmmmmm

[Anvil]

Steve,

Looks like the 1880 disappears at PCIe 108 or 109, it boots safely at 107.

very nice guys!
I have found a point of instability here with my card
when i reach a certain benchmark (pcmarktv and movies) i am having instability/crashes which is causing me to not be able to run at speeds i have pulled off before with my chip. i have done it at 4.6 before. but with the new card no dice.
so in the course of things i turned off the alarm on the raid card. and it beeps constantly during that benchmark. looking thorough the raid cards error log turns up a low power error. so not enough power to the card via the pcie bus is causing the issue. so what is the setting that will actually put more voltage across the bus, to the card? any ideas?

[Computurd]

it says specifically "3.3 voltage Under Voltage"

so i checked the 3.3 volts during run with eleet and it gets down to 3.14 during the heavy loads, when it beeps...

[xeon_1]

It could be that the power draw on the 3.3V line with the acerca and the oc is to high.
Whereas previously there wasn't such a power hungry card on the line.
Or the card is sensitive to small power dips when the cpu starts at 100% causing a momentary drop in voltage until the psu can compensate.

At any rate trying another psu might slove it as that one might have a higher current rating on the 3.3V line and/or a better/faster voltage controller.

[Computurd]

Good idea. any other voltages you think i could tweak to fix it? also i have a sound card on a pci slot...do you think taking that off or disabling it would help?

[Nitrobass24]

Taking it out couldnt hurt.

[eva2000]

remember software reported volts may not be accurate, try multimeter yet ?

[Computurd]

no but not entirely sure how to check the 3.3v with my mutlimeter..noob at that...

[eva2000]

how to measure using multimeter http://i4memory.com/f60/guide-using-...ly-rails-2632/

[Computurd]

ty for the link eva. Bad psu! my zues 1200w has taken a shat all over me...LOL 3.3 v is borked. jumped the zues and used it for everything except mobo, then hooked my good ol pc&p 750 just to the 24-pin and it is running like a champ.
ordered a st1500 so i dont have to worry about it for awhile. gonna explore rma with the zm1200 and see what they say.
been just pounding with this thing trying to get above 4.3 for the love of christ, with a chip i have hit 4.6 with easily in the past, very frustrating it took me that long to pinpoint it. the only good thing is that i did tweak the hell outta the raid and card etc for ultimate setup...so now i am in perfect position!

[Computurd]

well now we are working! up to sixth

I believe i can take 5 very soon...

[SteveRo]

Wow Mr CT - looking good! #6!
Looks like no question, areca 1880-4GB should be the new king of pcmv.
Come on Mr Nizzen, Paul's got you by 30 points!
