FrozenCPU looking to start selling ATI cards for miners.

[frojoe]

Hi all!

I work over at FrozenCPU.com. I was asking the boss if he would be interested in getting some cards for miners because I have gotten alot of email requests for watercooling those cards for mining. We would like to know if you would like the service of getting a 7950/7970 with a waterblock already installed ready to go? If you guys are interested in that service we are also looking for brand and model of the gpus you guys want. I see alot of people getting good hash rates on the gigabyte cards for LTC mining. Let me know what you all thing and if you can toss some model numbers my way.

Thanks alot!

Prices?

[frojoe]

Not sure yet. We are trying to get the consumers input on what cards they would want so we can get pricing.

[pekv2]

I'm sure people that don't have handson learning would love this option.

If you don't have experience with being very careful with hardware, you can damage your hardware, specifically watercooling/liquidcooling.

Does frozenCPU accept bitcoin payments?

[frojoe]

That exactly what we are trying to provide. Most of know guys know what you are doing but there are some that don't. We just want to have a few cards that people card get for mining all ready to go. Especially if they are looking for the other watercooling parts. Im trying to reach out to get some model numbers because my xfx7970s aren't the best at LTC mining. More input from you all the better and we appreciate it. We do no accept BTC unfortunately.

I suspect that having FrozenCPU fit a waterblock to a 7950/7970 will blow out the ROI on the cards. Previously, HD 5970s made sense as dual-gpus enabled very high hashing densities and watercooling kept the cards from roasting. The cards were relatively cheap per MH/s. Perhaps if HD 7990s drop in price they also may become a viable card to watercool for LTC hashing. Just my opinion, I could be very wrong.

You guys should consider using BitPay or other BTC handlers to accept BTC for your products. It would have been nice to have been able to pay with BTC when I bought all my HD 5970 waterblocks and fittings.

Personally I wouldn't WC a 7990 if you want any sort of density. 400W+ PER CARD is not something easily done on small, efficient or scalable WCing.

I don't see why not. A pair of HD 7990 would be easily handled by a 3x120mm radiator. I say this as one of my 3x HD 5970 rigs that pulls 950w from the wall runs on a 3x120mm radiator with core temps about 20C above ambient. Considering how you'll decrease core and vrm temps, you'll also reduce the power consumption slightly. I imagine a 4x HD 7990 card could be cooled by a pair thick-cored 3x120mm or 3x140mm radiators.

Interesting, https://www.litecoinpool.org/calc?hashrate=1400&difficulty=404.82011437 reports $12.95/day before power consumption. I'm assuming 1400 KH/s from https://github.com/litecoin-project/litecoin/wiki/Mining-hardware-comparison#wiki-ATI_AMD_GPUs and someone reporting 1415 KH/s from a pair of 7970s @ 1035MHz core, 1650MHz memory. 400 watts is only $32/month @ $0.11/kWh. Maybe it is time to consider picking up some HD7k series cards for LTC mining..

Since you bring up this topic, and you definitely have more experience in water cooling than I have.

I am planning to WC (GPU core only) 3x7950 or 2x7970+1x7950 on a single 360 rad, I think each of them draw less power than a 5970 does.

if you say only 20C above ambient, what kind of fan speed we are talking about here?  I prepared 3 fans of 1200 rpm, will that be enough?

[crazyates]

I love FrozenCPU for getting those parts that you just can't find anywhere else, but your prices aren't on the low side. Me personally, I'd rather just buy a 7970 and WB separate, and save some cash.

[Rjb82]

I have been ordering from FrozenCpu for a while now... 3-4 years. Not a large number of orders, but always top notch.

Just start accepting BTC and i'll be happy.

You guys and Newegg are just about the only companies i'll order from online.

Honestly, watercooling is an added expense for mining that is only really necessary in very specific circumstances (ie poor ambient or bad thermal design of setup).  I think if you could get the cards themselves in for a better or competitive price you guys would do well.

I'm running push-pull with I believe 70 cfm fans. It is by no means quiet but it is quieter than the stock solution. Be very careful in watercooling just the cores. Make sure you get sufficient airflow over the VRM and memory(especially if LTC mining) or you will burn up your cards very quickly. I imagine 3x HD 7950s just cooling the cores would only be around 500-600w and in my opinion you'd be fine on a similar setup. Keep in mind I am by no means a watercooling guru. I bought a bunch of parts, it worked, and I haven't touched it in over a year.

Buy a silver killcoil and distilled water. I have had minimal buildup in the lines or the blocks that have clear arcylic tops with only topping off the reservoir every other month. Just about as maintenance free as it gets.

[CanaryInTheMine]

you would be selling the cards or I can mail you a card and you ship it back with everything installed?
I would send you 2 7990s by powercolor.

[ISAWHIM]

I'll take 4x 7970's for $300ea @ $1200 total... (Provided that they function for mining, at stock speeds. Ugliness not an issue. Dead fans not an issue either... I provide my own air.)

I'll take another 4x in a month, after I cash-in my income-tax check. (Still waiting for that to come through.)

1) No one is selling 7970s for $300.
2) We're talking about watercooling, and you're talking about dead fans.

xfx7970s are great for mining...

Gotta kill the RAM-CLOCKS, since RAM isn't used (Not that much, or that fast), which will allow more GPU-CYCLES to be bumped-up...

Also, flip any heat-pipe cards upside down, they will not physically function correctly in a standard PCIe setup. Also PULL air through the fins, don't PUSH it through the fins, which blows the hot air back onto the chip below, that you are trying to cool.

Heat-pipes are marketing hype, when they are not designed correctly, like in those systems. The "Wicks" dry-up and the liquid does not wick up through the HOT pipes, into the HOTTER core, when you blow hot air back onto the core. It evaporates before it even gets to the GPU and condensates back on the cooling fins, or just stays evaporated as the whole unit overheats.

But I digress...

P.S. ALso, exhaust the hot air, don't let it circulate in the box/room... That is equally redundant. Even if it is 110F outside, it is still constantly 110F, unlike a room, that is trying to be AC-Cooled, from 150F from all the trapped heat. It is cheaper to cool the outside air, and exhaust the 90-110F heat-pipe/water-cooled air out the window/attic-vent. Plus, you get free Attic-AC since attics are 120-180F in the summer.

Like I said... ugliness and fans, not an issue...

If you are looking to "market", some novelty into these cards... Don't waste your time... Novelty doesn't make money, it just adds to overhead and ensures we DON'T have an interest in the cards that are modded with over-priced novelty junk.

He asked if there was an interest... My obvious answer is no... for waterblocks... but not for the cards.

As for selling multiple cards for $300 each... You are wrong. That is the only price I have ever payed for them. That is what they are worth, before marketing hype, without packaged retail junk, in bulk.

After this month, if I still pay $300, it is a bonus to those who get it. Because the cards will only be worth $250 by then, to me. (Though I am sure a few noobs will still happily pay $1,300-$350 for the cards, as they are selling them for on e-bay.)

The only cards over that price, are waterblocked, or come packed with over $100 worth of games, that are useless to me.

Hi all!

I work over at FrozenCPU.com. I was asking the boss if he would be interested in getting some cards for miners because I have gotten alot of email requests for watercooling those cards for mining.

There was no mention that he would be "watercooling them", just that there was a request for watercooling. His interest as stated, was, "I was asking the boss if he would be interested in getting some cards for miners".

The "because" is redundant and useless banter... "because I have gotten alot of email requests for watercooling those cards for mining."

But I digress...

I'll take the XTX cards you are having "difficulties with"... They all work fine for me.

thanks for the reply, the fans I got have 58 CFM, and I got like 50 small pieces of heatsink I have to stick them on VRM and memory.....that will really take a while........
