Where to Buy BM1370 ASIC Chips?

Anyone know where I can buy BM1370 ASIC? Looking for either BM1370BC or BM1370AA. I saw d-central has them but those prices are insane and they’re not in Europe. Aliexpress has some options too, but the sellers look sketchy.

I've ordered from NBTC Store on Aliexpress for other models like BM1397 and BM1362. They were decent but don’t have BM1370 listed now. Also tried BOM List but they took ages to ship. They’ve got BM1370PA but it’s pricey.

Heard good things about Zeus mining. Check this link: https://www.zeusbtc.com/ASIC-Miner-Repair/Parts-Tools-Details.asp?ID=3666. How many do you need? You might wanna buy a broken S21Pro and salvage the chips.

I need 3 chips. I’ll check zeusbtc, but it says out of stock and just offers quotes. Do you know where they ship from?

They ship from China or HK, but sometimes people get parts from the US. Not sure if that’s a one-off. The quote thing is annoying, and they have a minimum order of 5, which is a bummer.

Thanks for the info! I’d be okay with two chips, maybe even buy a third as a backup. If I get a quote, I can share it here. Contacted ZeusBTC on WhatsApp, but they don’t have the ASICs right now.

They just replied saying they can sell BM1370AA for $54 each. Not ideal but it’s something.

A new S21XP costs about 8k and has 325 chips. So that’s roughly $24.61 per chip. Considering parts usually double in price, $54 isn’t too far off.

Yeah, but shipping to the US can add up. So $54 sounds okay until you factor in shipping costs, then it can get pricey.

What’s the difference between BM1370 and BM1368? Both are used in the S21 series. Are they the same size and pinout?

From what I know, BM1370 does around 13 watts while BM1368 does about 17 watts. My XP miners run at about 12.5 watts if it’s cold.

I’m cool with the price, but the supplier gives me pause. Had a brief chat on OSMU Discord and got some feedback.

Did he mention why? I’ve ordered from them before without issues, but that’s a small sample size.

He didn’t go into detail. But if you and others had no problems, maybe I shouldn’t worry. It’s hard to check their reliability unless I ask around here or in Discord.

D-central just got some in stock. Managed to place an order today.

Avoid Zeus Mining. They sell overpriced knockoffs, but they have good SEO.

Got any other places to recommend?

There are groups that part out S21 Pros and sell the chips. Plebsource.com is one of them, just ask around.

Wow, they’re asking $120 for one? That’s over double what D-Central charges. The listing shows three BM1370 chips, so maybe that’s the price for all three?

When did Zeus start selling knockoffs? I haven’t had issues with them in years, last time I worried was pre-COVID.
